Linux creator Linus Torvalds announced the release of the 2.6.6 stable kernel. A number of notable additions found their way into the mainline 2.6 kernel during this development cycle, including Jens Axboe's laptop mode [story] and the completely fair queueing (CFQ) I/O scheduler [story], support for a non-executable stack on a number of architectures, several patches laying the groundwork for object-based reverse mapping, and 4KB kernel stacks for the i386 architecture reducing the kernel's per process overhead. Since 2.6.6-rc3 [story], Linus highlights the following changes:

"NTFS, XFS, FAT and CIFS updates. IDE cache-flush at shutdown fixes. ppc, sparc, s390 and ARM updates (and a few x86-64 fixes)."

Read on for the full list of changes since -rc3.

Ok, there it is (well, the tar-file and patches are still being up-loaded, 
but should be there soon).

NTFS, XFS, FAT and CIFS updates. IDE cache-flush at shutdown fixes. ppc, 
sparc, s390 and ARM updates (and a few x86-64 fixes).

Holler if I missed anything,

Summary of changes from v2.6.6-rc3 to v2.6.6
============================================

Adam Belay:
  o parport pnp detection fix

Alex Williamson:
  o [SERIAL] 8250_hcdp needs irq sharing

Alexander Viro:
  o Fix might_sleep in /proc/swaps code
  o mcdx.c insanity removal

Andi Kleen:
  o Fix machine check handler on x86-64
  o Fix x86-64 compilation without iommu for 2.6.6rc3

Andrew Morton:
  o acpi build fix setup.c:608: `acpi_skip_timer_override' undeclared
  o cifssmb.c warning fix
  o writeback livelock fix
  o fadvise length handling fix
  o task_struct alignment fix
  o usb linkage fix
  o cancel_delayed_work() fix
  o b44 driver needs mii
  o run populate_rootfs() before initcalls

Andries E. Brouwer:
  o report size of printk buffer

Anton Altaparmakov:
  o NTFS: Use get_bh() instead of manual atomic_inc() in
    fs/ntfs/compress.c
  o NTFS: - Modify fs/ntfs/time.c::ntfs2utc(), get_current_ntfs_time(),
    and utc2ntfs() to work with struct timespec instead of time_t on
    the Linux UTC time side thus preserving the full precision of the
    NTFS time and only loosing up to 99 nano-seconds in the Linux UTC
    time.
  o NTFS: - Remove unused ntfs_dirty_inode()
  o NTFS: Wrap flush_dcache_mft_record_page() in #ifdef NTFS_RW
  o NTFS: Add NInoTestSetFoo() and NInoTestClearFoo() macro magic to
    fs/ntfs/inode.h and use it to declare NInoTest{Set,Clear}Dirty.
  o NTFS: Move typedefs for ntfs_attr and test_t from fs/ntfs/inode.c
    to fs/ntfs/inode.h so they can be used elsewhere.
  o NTFS: Determine the mft mirror size as the number of mirrored mft
    records and store it in ntfs_volume->mftmirr_size
    (fs/ntfs/super.c).
  o NTFS: Load the mft mirror at mount time and compare the mft records
    stored in it to the ones in the mft (fs/ntfs/super.c).
  o NTFS: - Fix compiler warnings related to type casting
  o NTFS: Read the journal ($LogFile) and determine if the volume has
    been shutdown cleanly and force a read-only mount if not
    (fs/ntfs/super.c and fs/ntfs/logfile.c).  This is a little bit of a
    crude check in that we only look at the restart areas and not at
    the actual log records so that there will be a very small number of
    cases where we think that a volume is dirty when in fact it is
    clean.  This should only affect volumes that have not been shutdown
    cleanly and did not have any pending, non-check-pointed i/o.
  o NTFS:  Eeek.  Forgot to revert the Makefile before checking it in
    last time
  o NTFS: 2.1.8 release - If the $LogFile indicates a clean shutdown
    and a read-write (re)mount is requested, empty $LogFile by
    overwriting it with 0xff bytes to ensure that Windows cannot cause
    data corruption by replaying a stale journal after Linux has
    written to the volume.
