      [PATCH] SELinux inode security init · 573429e3
      Andrew Morton authored
      From: Stephen Smalley <sds@epoch.ncsc.mil>
      
      This patch reworks the SELinux module code that handles inodes initialized
      before the policy is initially loaded to also cover the case where a pseudo
      filesystem such as selinuxfs or nfsd directly populate themselves.
      
      The list of inode security structures is split into per-superblock lists
      associated with each superblock security structure, and the initialization
      is performed by superblock_doinit.

      [PATCH] Docbook: Make mandocs output more terse · 6e88ebdf
      Andrew Morton authored
      From: Michael Still <mikal@stillhq.com>
      
      This patch takes into account requests from various LKML members for the
      mandocs output to be more terse.  Information about the copyright, and
      formatting of the man page is moved into a comment at the start of the
      groff output.
      
      Sample output can be found at:

      [PATCH] Use mark_page_accessed() in follow_page() · a6bc080d
      Andrew Morton authored
      Touching a page via follow_page() counts as a reference so we should be
      either setting the referenced bit in the pte or running mark_page_accessed().
      
      Altering the pte is tricky because we haven't implemented an atomic
      pte_mkyoung().  And mark_page_accessed() is better anyway because it has more
      aging state: it can move the page onto the active list.

      [PATCH] bugfix for initialization bug in adm1021 driver · 548373bb
      Andrew Morton authored
      From: Rusty Lynch <rusty@linux.co.intel.com>
      
      While initializing the adm1021 device, the driver is performing a conversion
      from fixed point to Celcius on values that were declaired as Celcius.  On my
      Dell Precision 220 this results in a shutdown after a couple of minutes
      running.
      
      The latch simply removes the conversion.

      sbinfo->free_blocks -= len;
      
      but then later do;

      error:

      - undo recent change, made in the believe that "buffer" was the size of
        the whole file, it is just PAGE_SIZE in size.  This was causing kernel
        memory corruption.
      
        - Since files are allowed to have unknown sizes, by setting their
          size to 0, we can't preallocate a buffer of their size on open.
      
      - Adapt request_firmware() to the sysfs change.

      [PATCH] loop oops fix · 534d8695
      Andrew Morton authored
      loop-on-file oopses during unmount.  This is because lo_queue is now freed
      during lo_ioctl(LOOP_CLR_FD).  I think the scenario is:
      
      1: umount(8) opens /dev/loop0
      
      2: umount(8) runs lo_ioctl(LOOP_CLR_FD) (this frees the queue)
      
      3: umount(8) closes the /dev/loop0 handle.  The blockdev layer syncs the
         blockdev, but its mapping->backing_dev_info now points into la-la-land.
      
      We shouldn't be freeing the queue until all refs to it have gone away.  This
      patch gives the queue the same lifetime as the controlling loop_device
      itself.  It also makes the loop driver's queue appear in sysfs again.
      
      It would be better to free the queue when the device is not in use, but I'm
      not sure how we can hook into the blockdev layer to do that.

      From: Zwane Mwaikambo <zwane@linuxpower.ca>
      
      hugetlbfs was accessing super_block->s_fs_info after free'ing it.  This was
      because it was being free'd prematurely.  I have deferred free until
      ->put_super().  I have also removed hugetlbfs_kill_super since it now is
      simply a kill_litter_super.

      [PATCH] Make MTRR init conform with recommended procedure · 8bc25c76
      Andrew Morton authored
      From: Zwane Mwaikambo <zwane@linuxpower.ca>
      
      This is a patch to make the MTRR initialisation more conformant with what
      is stated in volume 3 of (10-36 Memory Cache Control).  The most notable
      change is entering the no-fill cache mode before clearing the PGE bit in
      cr4.  Intel also states that we should do the cache flush via the cr3
      register shuffle.  If there is a problem with the patch please don't
      hesitate to beat me vigorously with a clue-by-four.
      
      It has been tested on a 3x Pentium 133, 8x PIII Xeon 700, 1x Celeron 550 and 32x
      PIII 500 NUMAQ (hardware courtesy of OSDL)

      _devfs_walk_path does not check if de it is about to scan is a directory.
      Next step is spinlock on non-spinlock memory.  It requires either artificial
      setup or really broken driver but fairly easy to reproduce once you know how.
      
      It is likely to exist in 2.4 as well.

      [PATCH] probe UDF after reiserfs · ae5a8df7
      Andrew Morton authored
      Bug 1065 (http://bugme.osdl.org/show_bug.cgi?id=1065) points out that there
      is a risk that UDF will accidentally mount a reiserfs partition, which would
      prevent a successful boot.
      
      Andries points out that probing is unreliable and that users/admins should
      always specify the root filesystem type on the kernel boot command line with
      "rootfstype=resierfs".
      
      But nobody does that, so we should be trying reiserfs before UDF.

      [PATCH] fix task struct refcount bug · 4c0d7322
      Andrew Morton authored
      From: Manfred Spraul <manfred@colorfullife.com>
      
      (We think this might be the mystery bug which has been hanging about for
      months)
      
      
      We found a [the?] task struct refcount error: A task that dies sets
      tsk->state to TASK_ZOMBIE.  The next scheduled task checks prev->state, and
      if it's ZOMBIE, then it decrements the reference count of prev.  The
      prev->state & _ZOMBIE test is not atomic with schedule, thus if prev is
      scheduled again and dies between dropping the runqueue lock and checking
      prev->state, then the reference it dropped twice.
      
      This is possible with either preemption [schedule_tail is called by
      ret_from_fork with preemption count 1, finish_arch_switch drops it to 0] or
      profiling [profile_exit_mmap can sleep on profile_rwsem, called by
      mmdrop()] enabled.
