      [PATCH] exception table search fix · 8283a979
      Andrew Morton authored
      The exception table search code currently fails if addresses differ by more
      than 2G.  This is only a problem when using the 4g/4g address space split,
      but it's more robust this way.
      
      Also, shuffle the comparison order n there so the least likely case comes
      last.

      [PATCH] ext3: update a_ops when running `chattr +j' · fa85002b
      Andrew Morton authored
      From: Jan Kara <jack@suse.cz>
      
      Journalled-data files need a different set of address_space_operations, so
      we need to update the file's aops when someone runs `chattr +j' on the
      file.

      [PATCH] remove unused flags arg from fs/stat64* · 69c4ba40
      Andrew Morton authored
      From: "Randy.Dunlap" <rddunlap@osdl.org>
      From: Michael Still <mikal@stillhq.com>
      
      Viro and Andi Kleen agreed.  The <flags> argument isn't used at all and
      cannot be used safely in the future.
      
      remove third arg <long flags> from all 3 fs/stat.c stat64() calls since
      it's not used and there's no way to use it safely;

      [PATCH] pc300_tty.c is broken · e6c3a678
      Andrew Morton authored
      From: Russell King <rmk+lkml@arm.linux.org.uk>
      
      Russell was unable to correctly migrate this driver to the new
      modem-control-signal API because
      
       TIOCMBIS/TIOCMBIC do not control only the DTR signal, but also the RTS,
       OUT1 and OUT2 signals, or even maybe nothing at all.  Plus, these IOCTLs
       are no longer passed down to the driver.  Instead, drivers should
       implement tiocmget and tiocmset driver methods.
      
      so mark it as broken so as to not break allmodconfig/allyesconfig.

      Andrew Morton authored
      From: Manfred Spraul <manfred@colorfullife.com>
      
      sendfile supports reading from a given start offset for in_file, like
      pread.  But for the locks_verify_area call, in_file->f_pos is always used,
      even if a start offset is used.  Result: wrong area is checked for
      mandatory locks.

      [PATCH] Default hooks protecting the XATTR_SECURITY_PREFIX namespace · 3ba6fffc

      Add default hooks for both the dummy and capability code to protect the
      XATTR_SECURITY_PREFIX namespace.  These EAs were fully accessible to
      unauthorized users, so a user that rebooted from an SELinux kernel to a
      default kernel would leave those critical EAs unprotected.

      [PATCH] md: Small fixes for timely writing of md superblocks. · 24ae7480
      Andrew Morton authored
      From: NeilBrown <neilb@cse.unsw.edu.au>
      
      Currently a raid0 superblock is only written when the array is stopped, so a
      crash between creation and stop can lose your data.
      
      This patch marks a superblock 'dirty' at creation and forces a dirty
      superblock to be written when the array is started.
      
      Previously we would prod the per-array thread at this point, but as it avoids
      certain chores when the array is locked, and the array is locked at this
      point, that isn't guaranteed to do the right thing.  Instead we prod the
      thread whenever the array is unlocked.
      
      Finally, only write the superblock at array stop if it is needed to mark the
      array as 'clean'.  raid0 which is never dirty, doesn't need this.

      [PATCH] md: Don't allow raid5 rebuild to swamp raid5 stripe cache · 5edef83d
      Andrew Morton authored
      From: NeilBrown <neilb@cse.unsw.edu.au>
      
      raid5 rebuild takes stripes so agressively that other access cannot get a
      look-in.
      
      With this patch, the rebuild pauses slightly if there is a shortage of
      stripes to let other processes have a chance.
      
      akpm: I was worried about starvation due to the harsh semantics of yield() in
      2.6.  But Neil has performed specific testing for that and things seem OK. 
      If people do note CPU starvation problems we will need to replace the yield()
      with a schedule_timeout(1).

      Andrew Morton authored
      From: NeilBrown <neilb@cse.unsw.edu.au>
      
       Following are 10 patches for md in 2.6.1-lastest.
      
       1-6 are simple bugfixes that I am confident should be in 2.6.2.
      
       7 is a bugfix that is fairly important, but could probably do with a
       bit more testing first.  It is not impossible that it could deadlock,
       though I think I have caught and fixed all the problems.
      
       8-10 are code simplication.
      
       So maybe 7-10 should only go in -mm for now, but if it is a while
       before 2.6.2, then maybe they can go in a 2.6.2-pre.

      [PATCH] One-shot support for epoll · edd01104
      Andrew Morton authored
      From: Davide Libenzi <davidel@xmailserver.org>
      
      The attached patch implements the one-shot support for epoll.  Because of
      the way epoll works (hooking f_op->poll()) the ET behavior is not really ET
      because it might happen that, while data is still available to read (for
      the EPOLLIN case), another chunk will become available triggering another
      event.
      
      While those conditions can be easily be handled in userspace, the absolute
      triviality of the patch and the avoidance of user/kernel space switches and
      f_op->poll() calls, make IMHO worth doing this inside epoll itself.

      This patch allows iSeries to come much closer to building.
      
      This is a precurser to my trying to merge the virtual device drivers for
      iSeries (console, disk and cdrom).
