      [PATCH] Add printk levels to mtrr, also clarify · d4bae497
      Alan Cox authored
      The big thing here is actually turning
      'Your bios sucks'
      into
      'Your bios sucks, but we fixed it and life is good, don't panic'
      
      Which with a vendor hat on is important.  Its currently hard to tell
      whether some Linux errors are things to worry about or merely spanking
      the manufacturer.  I'd urge people writing error messages to think about
      that btw - does it tell the user if the problem is fixed ?

      [PATCH] Make the world safe for -Wundef · 7807a1bc
      Andrew Morton authored
      Patch from: Valdis.Kletnieks@vt.edu
      
      This is a patch to clean things up so compiling with -Wundef becomes feasible
      (This patch cuts the number of warnings with 'make allyesconfig' drop from
      around 10,000 to several hundred).  It was originally inspired by the
      discussion of things that include linux/version.h but don't use the contents
      - after doing this, I was able to find that there *WAS* at least one place
      where version.h was missing (see following patch).

      [PATCH] direct-io: allow reading of the part-filled EOF block · 3f31e635
      Andrew Morton authored
      driect-io will currently return EINVAL when the application tries to read the
      final bit of the file at EOF.  (assuming the file's length is not a multiple
      of the filesystem blocksize).
      
      The 2.4 kernelwill reurn 0 (it won't read it at all).
      
      This patch changes the 2.5 kernel to allow that block to be read.

      Andrew Morton authored
      If at the end of direct_io_worker, dio->result is non-zero then we
      unconditionally copy that into the return value, potentially ignoring any I/O
      errors which were accumulated into local variable `ret'.
      
      Only do the assignment if `ret' is zero.

      [PATCH] cciss driver update · 3aee2f2f
      Andrew Morton authored
      Patch from: steve cameron <steve.cameron@hp.com>
      
      Steve sent out a nice series of 11 broken-out patches.  I have lumped them
      all together.
      
      - Makes the cciss driver compile in 2.5.60  (from tony@cantech.net.au)
      
      - From randy.dunlap@verizon.net, fix memory leaks in cciss driver
      
      - Allow cciss driver attached disks other than the first to be accessed.
      
      - Zero out cylinders when zeroing out other disk info in cciss driver.
      
      - Remove unused variable from cciss_scsi.c
      
      - This patch makes scsi commands to tape drives have no timeouts.
        Previously the timeout was 1000 seconds, too short, and nothing good
        happens when the timeout expires.  Better to have no timeout.  e.g.  mt -f
        /dev/st0 erase may take about 2 hours 30 min on AIT 100.
      
      - Remove unneeded cciss_scsi init code from cciss driver.
      
      - Remove udelay in command polling routine
      - extend timeout to 20 seconds (need for certain multiport storage box)
      - Remove unneeded init time code in cciss_scsi.c (thus allowing removal
        of udelay in command polling code.)
      
      - Factor out duplicated read capacity code into common routine in cciss
        driver.
      
      - factor duplicated geometry inquiry code into common routine in cciss
        driver.

      [PATCH] blk_congestion_wait tuning and lockup fix · ecc3f712
      Andrew Morton authored
      blk_congestion_wait() will currently not wait if there are no write requests
      in flight.  Which is a potential problem if all the dirty data is against NFS
      filesystems.
      
      For write(2) traffic against NFS, things work nicely, because writers
      throttle in nfs_wait_on_requests().  But for MAP_SHARED dirtyings we need to
      avoid spinning in balance_dirty_pages().  So allow callers to fall through to
      the explicit sleep in that case.
      
      This will also fix a weird lockup which the reiser4 developers report.  In
      that case they have managed to have _all_ inodes against a superblock in
      locked state, yet there are no write requests in flight.  Taking a nap in
      blk_congestion_wait() in this case will yield the CPU to the threads which
      are trying to write out pages.
      
      Also tune up the sleep durations in various callers - 250 milliseconds seems
      rather long.

      [PATCH] xattr: trusted extended attributes · c2e7eeb0
      Andrew Morton authored
      Patch from Andreas Gruenbacher <agruen@suse.de>
      
      This patch adds trusted extended attributes.  Trusted extended attributes are
      visible and accessible only to processes that have the CAP_SYS_ADMIN
      capability.  Attributes in this class are used to implement mechanisms in
      user space (i.e., outside the kernel) which keep information in extended
      attributes to which ordinary processes have no access.  HSM is an example.

      Andrew Morton authored
      Patch from Andreas Gruenbacher <agruen@suse.de>
      
      This adds the XATTR_KERNEL_CONTEXT extended attributes flag.  Kernel code may

      would otherwise be imposed on the calling process.

      [PATCH] xattr: infrastructure for permission overrides · 36bc191b
      Andrew Morton authored
      Patch from Andreas Gruenbacher <agruen@suse.de>
      
      This adds flags parameters to the getxattr, listxattr, and removexattr inode
      operations.  This is in preparation for the next patch, which allows
      in-kernel code (i.e., modules) to override extended attribute permission
      restrictions (which in turn is used by HSM implementations and the like).

      [PATCH] xattr: listxattr fix · af8e38c7
      Andrew Morton authored
      Patch from Andreas Gruenbacher <agruen@suse.de>
      
      This patch fixes a bug in the ext2 and ext3 listxattr operation: Even if
      an attribute is hidden from the user, the terminating NULL character was
      included in the listxattr result. After the patch this doesn't happen
      anymore.

      [PATCH] dcache_rcu · d8a55dda
      Andrew Morton authored
      Patch from Maneesh Soni <maneesh@in.ibm.com>, Dipankar Sarma
      <dipankar@in.ibm.com> and probably others.
      
      
      This patch provides dcache_lock free d_lookup() using RCU. Al pointed
      races with d_move and lockfree d_lookup() while concurrent rename is
      going on. We tested this with a test doing million renames
      each in 50 threads on 50 different ramfs filesystems. And simultaneously
      running millions of "ls". The tests were done on 4-way SMP box.
      
      1. Lookup going to a different bucket as the current dentry is
         moved to a different bucket due to rename. This is solved by
         having a list_head pointer in the dentry structure which points
         to the bucket head it belongs. The bucket pointer is updated when the
         dentry is added to the hash chain. Lookup checks if the current
         dentry belongs to a different bucket, the cached lookup is
         failed and real lookup will be done. This condition occured nearly
         about 100 times during the heavy_rename test.
      
      2. Lookup has got the dentry it is looking and it is comparing
         various keys and meanwhile a rename operation moves the dentry.
         This is solved by using a per dentry counter (d_move_count) which
         is updated at the end of d_move. Lookup takes a snapshot of the
         d_move_count before comparing the keys and once the comparision
         succeeds, it takes the per dentry lock to check the d_move_count
         again. If move_count differs, then dentry is moved (or renamed)
         and the lookup is failed.
      
      3. There can be a theoritical race when a dentry keeps coming back
         to original bucket due to double moves. Due to this lookup may
         consider that it has never moved and can end up in a infinite loop.
         This is solved by using a loop_counter which is compared with a
         approximate maximum number of dentries per bucket. This never got
         hit during the heavy_rename test.
      
      4. There is one more change regarding the loop termintaion condition
         in d_lookup, now the next hash pointer is compared with the current
         dentries bucket pointer (is_bucket()).
      
      5. memcmp() in d_lookup() can go out of bounds if name pointer and length
         fields are not consistent. For this we used a pointer to qstr to keep
         length and name pointer in one structre.
      
      We also tried solving these by using a rwlock but it could not compete
      with lockless solution.
