13 years ago[GFS2] Map multiple blocks at once where possible
Steven Whitehouse [Mon, 18 Sep 2006 21:18:23 +0000]
[GFS2] Map multiple blocks at once where possible

This is a tidy up of the GFS2 bmap code. The main change is that the
bh is passed to gfs2_block_map allowing the flags to be set directly
rather than having to repeat that code several times in ops_address.c.

At the same time, the extent mapping code from gfs2_extent_map has
been moved into gfs2_block_map. This allows all calls to gfs2_block_map
to map extents in the case that no allocation is taking place. As a
result reads and non-allocating writes should be faster. A quick test
with postmark appears to support this.

There is a limit on the number of blocks mapped in a single bmap
call in that it will only ever map blocks which are pointed to
from a single pointer block. So in other words, it will never try
to do additional i/o in order to satisfy read-ahead. The maximum
number of blocks is thus somewhat less than 512 (the GFS2 4k block
size minus the header divided by sizeof(u64)). I've further limited
the mapping of "normal" blocks to 32 blocks (to avoid extra work)
since readpages() will currently read a maximum of 32 blocks ahead (128k).

Some further work will probably be needed to set a suitable value
for DIO as well, but for now thats left at the maximum 512 (see
ops_address.c:gfs2_get_block_direct).

There is probably a lot more that can be done to improve bmap for GFS2,
but this is a good first step.

Steven Whitehouse [Tue, 12 Sep 2006 14:10:01 +0000]
[GFS2] Use hlist for glock hash chains

This results in smaller list heads, so that we can have more chains
in the same amount of memory (twice as many). I've multiplied the
size of the table by four though - this is because we are saving
memory by not having one lock per chain any more. So we land up
using about the same amount of memory for the hash table as we
did before I started these changes, the difference being that we
now have four times as many hash chains.

The reason that I say "about the same amount of memory" is that the
actual amount now depends upon the NR_CPUS and some of the config
variables, so that its not exact and in some cases we do use more
memory. Eventually we might want to scale the hash table size
according to the size of physical ram as measured on module load.

Paul Mundt [Tue, 12 Sep 2006 05:21:25 +0000]
sh64: Drop deprecated ISA tuning for legacy toolchains.

The original sh64 toolchains required that we tune the ISA
level accordingly to not have head.S/entry.S blow up. With
current toolchains, this is no longer the case, and the
syntax magically changed as well, causing all current
toolchains to die a horrible death.

Incidentally, code generation in other parts of the kernel
is now significantly complex enough that none of the older
toolchains make it very far these days, so there's not
even any point in preserving legacy compatability via
as-option.

This fixes a long-standing issue, as noted here:

http://lkml.org/lkml/2005/1/5/223

Though at the time the current toolchains were too broken
to make adjusting the tuning worthwhile.

Steven Whitehouse [Tue, 12 Sep 2006 01:40:30 +0000]
[GFS2] Rewrite of examine_bucket()

The existing implementation of this function in glock.c was not
very efficient as it relied upon keeping a cursor element upon the
hash chain in question and moving it along. This new version improves
upon this by using the current element as a cursor. This is possible
since we only look at the "next" element in the list after we've
taken the read_lock() subsequent to calling the examiner function.
Obviously we have to eventually drop the ref count that we are then
left with and we cannot do that while holding the read_lock, so we
do that next time we drop the lock. That means either just before
we examine another glock, or when the loop has terminated.

The new implementation has several advantages: it uses only a
read_lock() rather than a write_lock(), so it can run simnultaneously
with other code, it doesn't need a "plug" element, so that it removes
a test not only from this list iterator, but from all the other glock
list iterators too. So it makes things faster and smaller.

V4L/DVB (4605): Fixes an issue with V4L1 and make headers-install

V4L1 support should be disabled when no CONFIG_VIDEO_V4L1_COMPAT is defined,
to allow checking for broken V4L2 ports. This is very important during the
migration phase for V4L2 API.
However, userspace apps should be capable of using both APIs, since they need
to test at runtime, via VIDIOCGCAP ioctl, if V4L1 is supported. So, when
__KERNEL__ is not defined, those ioctls and corresponding structs should be
visible.
This patch also removes the obsolete defines HAVE_V4L1 and HAVE_V4L2, that
where causing some confusion, and were replaced by CONFIG_VIDEO_V4L1_COMPAT
and CONFIG_VIDEO_V4L2.

- The request is the first one on the resource, so first_lkid is set.

- During recovery the requesting node becomes master.
- The request is now processed locally instead of being a remote operation.
- At this point we need to call confirm_master() on the resource since

In order to allow this, the gl_bucket member of struct gfs2_glock has

[PATCH] ext3_getblk() should handle HOLE correctly

It has been reported that ext3_getblk() is not doing the right thing and

Looking at the code, it looks like it's not handle HOLE correctly.  It ends
up returning -EIO.  Here is the patch to fix it.

If we really want to be paranoid, we can allow return values 0 (HOLE), 1
(we asked for one block) and return -EIO for more than 1 block.  But I
really don't see a reason for doing it - all we need is the block# here.
(doesn't matter how many blocks are mapped).

ext3_get_blocks_handle() returns number of blocks it mapped.  It returns 0
in case of HOLE.  ext3_getblk() should handle HOLE properly (currently its
dumping warning stack and returning -EIO).

13 years ago[PATCH] Use the correct restart option for futex_lock_pi
Thomas Gleixner [Fri, 8 Sep 2006 16:47:15 +0000]
[PATCH] Use the correct restart option for futex_lock_pi

The current implementation of futex_lock_pi returns -ERESTART_RESTARTBLOCK
in case that the lock operation has been interrupted by a signal.  This
results in a return of -EINTR to userspace in case there is an handler for
the signal.  This is wrong, because userspace expects that the lock
function does not return in any case of signal delivery.

This was not caught by my insufficient test case, but triggered a nasty
userspace problem in an high load application scenario.  Unfortunately also
glibc does not check for this invalid return value.

Using -ERSTARTNOINTR makes sure, that the interrupted syscall is restarted.
 The restart block related code can be safely removed, as the possible
timeout argument is an absolute time value.

Kirill Korotaev [Thu, 7 Sep 2006 10:17:04 +0000]
[PATCH] IA64,sparc: local DoS with corrupted ELFs

This prevents cross-region mappings on IA64 and SPARC which could lead
to system crash.  They were correctly trapped for normal mmap() calls,
but not for the kernel internal calls generated by executable loading.

This code just moves the architecture-specific cross-region checks into
an arch-specific "arch_mmap_check()" macro, and defines that for the
architectures that needed it (ia64, sparc and sparc64).

Architectures that don't have any special requirements can just ignore
the new cross-region check, since the mmap() code will just notice on
its own when the macro isn't defined.

13 years ago[XFS] Prevent free space oversubscription and xfssyncd looping.
David Chinner [Thu, 7 Sep 2006 04:26:50 +0000]
[XFS] Prevent free space oversubscription and xfssyncd looping.

The fix for recent ENOSPC deadlocks introduced certain limitations on
allocations. The fix could cause xfssyncd to loop endlessly if we did not
leave some space free for the allocator to work correctly. Basically, we
needed to ensure that we had at least 4 blocks free for an AG free list
and a block for the inode bmap btree at all times.

However, this did not take into account the fact that each AG has a free
list that needs 4 blocks. Hence any filesystem with more than one AG could
cause oversubscription of free space and make xfssyncd spin forever trying
to allocate space needed for AG freelists that was not available in the
AG.

The following patch reserves space for the free lists in all AGs plus the
inode bmap btree which prevents oversubscription. It also prevents those
blocks from being reported as free space (as they can never be used) and
makes the SMP in-core superblock accounting code and the reserved block
ioctl respect this requirement.
