2.5.64-mm8

[Andrew Morton]

ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/patches/2.5/2.5.64/2.5.64-mm8/

. Several fixes to the anticipatory scheduler.  It is the default IO
  scheduler again.

  The main thing which was fixed here was an interesting deadlock involving
  keventd, the I/O scheduler, vfork and request_module().

. I should have mentioned that 2.5.64-mm7 included a CPU scheduler tweak
  from Mike Galbraith which apparently fixes up the various starvation
  problems which people have been experiencing.  That is also in 2.5.64-mm8.



Changes since 2.5.64-mm7:


-ppc64-compat-flock.patch
-ppc64-eeh-fix.patch
-ppc64-socketcall-fix.patch
-register-tty_devclass.patch

 Merged

+proc-sys-debug.patch

 Create /proc/sys/debug/0 ...  /proc/sys/debug/5.  These appear in the
 kernel as 

	int proc_sys_debug[8];

 These are not used for anyting - it is for ah-hoc debugging convenience.

+as-jumbo-fix.patch
+as-request_fn-in-timer.patch
+as-remove-request-fix.patch

 Anticipatory scheduler fixes

-deadline-default.patch

 Make the anticipatory scheduler the default again.

+unplug-from-timer.patch

 Call q->unplug_fn direct from timer context rather than via
 schedule_work().

+ext2-no-lock_super-set-s_dirt.patch
+ext2-ialloc-no-lock_super.patch
+ext2-ialloc-no-lock_super-fixes.patch

 Avoid lock_super() in the ext2 inode allocator

+pci-update-1.patch

 Update for Russell's PCI rework.

+affs-lock_kernel-fix.patch

 Missing an unlock_kernel().  (Why didn't any of the checkers notice this?)

+lseek-ext2_readdir.patch

 Remove the lock_kernel()s in ext2_readdir/ext3_readdir

+inode_setattr-lock_kernel-removal.patch

 Remove the lock_kernel() around inode_setattr's vmtruncate() call.

+raid0-oops-fix.patch

 Fix oops in RAID0.

Could you replace this the patch below?
It removes the kernel lock completely and also fixes a bitmap corruption.

bye, Roman
