12 years agomm: Remove slab destructors from kmem_cache_create().
Paul Mundt [Fri, 20 Jul 2007 01:11:58 +0000]
mm: Remove slab destructors from kmem_cache_create().

Slab destructors were no longer supported after Christoph's
c59def9f222d44bb7e2f0a559f2906191a0862d7 change. They've been
BUGs for both slab and slub, and slob never supported them
either.

This rips out support for the dtor pointer from kmem_cache_create()
completely and fixes up every single callsite in the kernel (there were
about 224, not including the slab allocator definitions themselves,
or the documentation references).

12 years agoide: add support for SCSI ioctls to ide-floppy
Bartlomiej Zolnierkiewicz [Thu, 19 Jul 2007 23:11:59 +0000]
ide: add support for SCSI ioctls to ide-floppy

Now that ide-floppy supports SG_IO we can add support for SCSI ioctls
(except deprecated SCSI_IOCTL_SEND_COMMAND and legacy CDROM_SEND_PACKET
ones - we can add them later iff really needed).

While at it remove handling of CDROMEJECT and CDROMCLOSETRAY ioctls from
generic_ide_ioctl():

- This prevents ide-{disk,tape,scsi} device drivers from obtaining
  REQ_TYPE_BLOCK_PC type requests which are currently unsupported by
  these drivers and which are potentially harmful (as reported by Andrew).

- There is no functionality loss since aforementioned ioctls will now be
  handled by idefloppy_ioctl()->scsi_cmd_ioctl() (for devices using
  ide-floppy driver) and by idecd_ioctl->cdrom_ioctl()->scsi_cmd_ioctl()
  (for devices using ide-cd driver).

i386: Allow KVM on i386 nonpae

Currently, CONFIG_X86_CMPXCHG64 both enables boot-time checking of
the cmpxchg64b feature and enables compilation of the set_64bit() family.
Since the option is dependent on PAE, and since KVM depends on set_64bit(),
this effectively disables KVM on i386 nopae.

Simplify by removing the config option altogether: the boot check is made
dependent on CONFIG_X86_PAE directly, and the set_64bit() family is exposed
without constraints.  It is up to users to check for the feature flag (KVM
does not as virtualiation extensions imply its existence).

When a CONFIG_USER_NS=n and a user tries to unshare some namespace other
than the user namespace, the dummy copy_user_ns returns NULL rather than
the old_ns.

This value then gets assigned to task->nsproxy->user_ns, so that a

pointer deref.

Suresh Siddha [Thu, 19 Jul 2007 19:28:35 +0000]
[PATCH] sched: fix newly idle load balance in case of SMT

In the presence of SMT, newly idle balance was never happening for
multi-core and SMP domains (even when both the logical siblings are
idle).

If thread 0 is already idle and when thread 1 is about to go to idle,
newly idle load balance always think that one of the threads is not idle
and skips doing the newly idle load balance for multi-core and SMP
domains.

This is because of the idle_cpu() macro, which checks if the current
process on a cpu is an idle process. But this is not the case for the
thread doing the load_balance_newidle().

Fix this by using runqueue's nr_running field instead of idle_cpu(). And
also skip the logic of 'only one idle cpu in the group will be doing
load balancing' during newly idle case.

* I have experimental evidence that the W83627EHG needs more than 1
second to refresh all the measured values. Increase the caching time to
1.5 second.

measurement register is no longer valid, until the next time the chip

Jean Delvare [Sat, 9 Jun 2007 14:11:16 +0000]
hwmon: Fault files naming convention

We have the following naming convention documented in
Documentation/hwmon/sysfs-interface for fault files:

in[0-*]_input_fault
fan[1-*]_input_fault
temp[1-*]_input_fault

Some drivers follow this convention (lm63, lm83, lm90, smsc47m192).
However some drivers omit the "input" part and create files named
fan1_fault (pc87427) or temp1_fault (dme1737). And the new "generic"
libsensors follows this second (non-standard) convention, so it fails
to report fault conditions for drivers which follow the standard.

We want a single naming scheme, and everyone seems to prefer the
shorter variant, so let's go for it.
