[PATCH] ext4: refuse ro to rw remount of fs with orphan inodes

In the rare case where we have skipped orphan inode processing due to a
readonly block device, and the block device subsequently changes back to
read-write, disallow a remount,rw transition of the filesystem when we have an
unprocessed orphan inodes as this would corrupt the list.

Ideally we should process the orphan inode list during the remount, but that's
trickier, and this plugs the hole for now.

13 years ago[PATCH] RTC framework driver for CMOS RTCs
David Brownell [Sat, 10 Feb 2007 09:46:02 +0000]
[PATCH] RTC framework driver for CMOS RTCs

This is an "RTC framework" driver for the "CMOS" RTCs which are standard on
PCs and some other platforms.  That's MC146818 compatible silicon.
Advantages of this vs.  drivers/char/rtc.c (use one _or_ the other, only
one will be able to claim the RTC irq) include:

 - This leverages both the new RTC framework and the driver model; both
   PNPACPI and platform device modes are supported.  (A separate patch
   creates a platform device on PCs where PNPACPI isn't configured.)

 - It supports common extensions like longer alarms.  (A separate patch
   exports that information from ACPI through platform_data.)

 - Likewise, system wakeup events use "real driver model support", with
   policy control via sysfs "wakeup" attributes and and using normal rtc
   ioctls to manage wakeup.  (Patch in the works.  The ACPI hooks are
   known; /proc/acpi/alarm can vanish.  Making it work with EFI will
   be a minor challenge to someone with e.g. a MiniMac.)

It's not yet been tested on non-x86 systems, without ACPI, or with HPET.
And the RTC framework will surely have teething pains on "mainstream"
PC-based systems (though must embedded Linux systems use it heavily), not
limited to sorting out the "/dev/rtc0" issue (udev easily tweaked).  Also,
the ALSA rtctimer code doesn't use the new RTC API.

Otherwise, this should be a no-known-regressions replacement for the old
drivers/char/rtc.c driver, and should help the non-embedded distros (and
the new timekeeping code) start to switch to the framework.

Note also that any systems using "rtc-m48t86" are candidates to switch over
to this more functional driver; the platform data is different, and the way
bytes are read is different, but otherwise those chips should be compatible.

[PATCH] Common compat_sys_sysinfo

[PATCH] tty: improve encode_baud_rate logic

Mostly so people can see the work in progress.  This enhances the encode
function which isn't currently used in the base tree but is when using some of
the testing tty patches.

This resolves a problem with some hardware where applications got confusing
information from the tty ioctls.  Correct but confusing.

In some situations asking for, say, 9600 baud actually gets you 9595 baud or
similar near-miss values.  With the old code this meant that a request for
B9600 got a return of BOTHER, 9595 which programs interpreted as a failure.

The new code now works on the following basis

- If you ask for specific rate via BOTHER, you get a precise return

- If you ask for a standard Bfoo rate and the result is close you get a Bfoo
  return

- If you ask for a standard Bfoo rate and get something way off you get a
  BOTHER/rate return

This seems to fix up the cases I've found where this broke compatibility.

[PATCH] relax check for AIX in msdos partition table

The patch to identify AIX disks and ignore them has caused at least one
machine to fail to find the root partition on 2.6.19. The patch is:

http://lkml.org/lkml/2006/7/31/117

The problem is some disk formatters do not blow away the first 4 bytes
of the disk. If the disk we are installing to used to have AIX on it,
then the first 4 bytes will still have IBMA in EBCDIC.

The install in question was debian etch. Im not sure what the best fix
is, perhaps the AIX detection code could check more than the first 4
bytes.

The whole partition info for primary partitions is in this block:

  dd if=/dev/sdb count=$(( 4 * 16 )) bs=1 skip=$(( 0x1be ))

All other data do not matter, beside the 0x55aa marker at the end of the
first block.

[PATCH] IPMI: Fix some RCU problems

Fix some RCU problem pointed out by Paul McKenney of IBM.  These are:

The wholesale move of the command receivers list into a new list was not
safe because the list will point to the new tail during a traversal, so the
traversal will never end on a reader if this happens during a read.

Memory barriers were needed to handle proper ordering of the setting of the
IPMI interface as valid.  Readers might not see proper ordering of data
otherwise.

In ipmi_smi_watcher_register(), the use of the _rcu suffix on the list is
unnecessary.

This require the list_splice_init_rcu() patch previously posted.

This patch is in support of the IPMI driver.  I have tested this with the

Add a list_splice_init_rcu() function to splice an RCU-protected list into
another list.  This takes the sync function as an argument, so one would do
something like:

INIT_LIST_HEAD(&list);
list_splice_init_rcu(&source, &dest, synchronize_rcu);

The idea being to keep the RCU API proliferation down to a dull roar.

The 32bit and 64bit PARISC Linux kernels suffers from the problem, that the
gettimeofday() call sometimes returns non-monotonic times.

The easiest way to fix this, is to drop the PARISC-specific implementation
and switch over to the generic TIME_INTERPOLATION framework.

But in order to make it even compile on 32bit PARISC, the patch below which
touches the generic Linux code, is mandatory.

More information and the full patch with the parisc-specific changes is included in this thread: http://lists.parisc-linux.org/pipermail/parisc-linux/2006-December/031003.html

As far as I could see, this patch does not change anything for the existing
architectures which use this framework (IA64 and SPARC64), since "cycles_t"
is defined there as unsigned 64bit-integer anyway (which then makes this
patch a no-change for them).

Allow taint flags to be set from userspace by writing to

when userspace has potentially done something dangerous that might

questions about what may have caused the user taint flag to have been set.

For example, they might examine the logs of the realtime JVM to see if the
Java program has used the really silly, stupid, dangerous, and
completely-non-portable direct access to physical memory feature which MUST

[PATCH] PNP: export pnp_bus_type

The PNP framework doesn't export "pnp_bus_type", which is an unfortunate
exception to the policy followed by pretty much every other bus.  I noticed
this when I had to find a device in order to provide its platform_data.

Note that per advice from Arjan, the "export" scope has been been minimized to
avoid the hundred-plus bytes needed to support access from modules.  In this
case, the symbol is only needed by statically linked kernel code that lives
outside the drivers/pnp directory.

[PATCH] ext2: skip pages past number of blocks in ext2_find_entry

This one was pointed out on the MOKB site:
http://kernelfun.blogspot.com/2006/11/mokb-09-11-2006-linux-26x-ext2checkpage.html

If a directory's i_size is corrupted, ext2_find_entry() will keep
processing pages until the i_size is reached, even if there are no more
blocks associated with the directory inode.  This patch puts in some
minimal sanity-checking so that we don't keep checking pages (and issuing
errors) if we know there can be no more data to read, based on the block
count of the directory inode.

This is somewhat similar in approach to the ext3 patch I sent earlier this
year.

[PATCH] Relay: add CPU hotplug support

Mathieu originally needed to add this for tracing Xen, but it's something
that's needed for any application that can be tracing while cpus are added.

unplug isn't supported by this patch.  The thought was that at minumum a new
buffer needs to be added when a cpu comes up, but it wasn't worth the effort
to remove buffers on cpu down since they'd be freed soon anyway when the

[PATCH] consolidate line discipline number definitions

The line discipline numbers N_* are currently defined for each architecture
individually, but (except for a seeming mistake) identically, in
asm/termios.h.  There is no obvious reason why these numbers should be
architecture specific, nor any apparent relationship with the termios
structure.  The total number of these, NR_LDISCS, is defined in linux/tty.h
anyway.  So I propose the following patch which moves the definitions of
the individual line disciplines to linux/tty.h too.

Three of these numbers (N_MASC, N_PROFIBUS_FDL, and N_SMSBLOCK) are unused
in the current kernel, but the patch still keeps the complete set in case
there are plans to use them yet.

[PATCH] struct vfsmount: keep mnt_count & mnt_expiry_mark away from mnt_flags

I noticed cache misses in touch_atime() that can be avoided if we keep
mnt_count & mnt_expiry_mark in a different cache line than mnt_flags
(mostly read)

mnt_count & mnt_expiry_mark are modified each time a file is opened/closed
in a file system.

touch_atime() is called each time a file is read, and generally needs to
read mnt_flags.

Other fields of struct vfsmount are mostly read so I chose to move
mnt_count & mnt_expiry_mark at the end of struct vfsmount.  And adding a
comment so that nobody tries to re-arrange fields to fill the holes :)

On 64bits platforms, the new offsetof(mnt_count) is 0xC0
On 32bits platforms, it is 0x60, so I didnot add a
____cacheline_aligned_in_smp because it would have a too big impact on the
size of this object (in particular if CONFIG_X86_L1_CACHE_SHIFT=7)

[PATCH] disable init/initramfs.c

The file init/initramfs.c is always compiled and linked in the kernel
vmlinux even when BLK_DEV_RAM and BLK_DEV_INITRD are disabled and the
system isn't using any form of an initramfs or initrd.  In this situation
the code is only used to unpack a (static) default initial rootfilesystem.
The current init/initramfs.c code.  usr/initramfs_data.o compiles to a size
of ~15 kbytes.  Disabling BLK_DEV_RAM and BLK_DEV_INTRD shrinks the kernel
code size with ~60 Kbytes.

This patch avoids compiling in the code and data for initramfs support if
CONFIG_BLK_DEV_INITRD is not defined.  Instead of the initramfs code and
data it uses a small routine in init/noinitramfs.c to setup an initial
static default environment for mounting a rootfilesystem later on in the
kernel initialisation process.  The new code is: 164 bytes of size.

The patch is separated in two parts:
1) doesn't compile initramfs code when CONFIG_BLK_DEV_INITRD is not set
2) changing all plaforms vmlinux.lds.S files to not reserve an area of
PAGE_SIZE when CONFIG_BLK_DEV_INITRD is not set.

[PATCH] Char: tty, delete wake_up_interruptible after tty_wakeup

tty_wakeup calls wake_up_interruptible(&tty->write_wait) itself, it's not
needed to wake up again after tty_wakeup returns.

[PATCH] remove include/linux/byteorder/pdp_endian.h

include/linux/byteorder/pdp_endian.h is completely unused, and the comment in
the file itself states that it's both untested and only a proof-of-concept.
