      Input: synaptics - retry failed resets when reconnecting · c63fe0a4
      Alexandre Peixoto Ferreira authored 
      
On some machines, like Dell Studio XPS 16 (1640), touchpad fails to
respond to the standard query after first reset but may start
responding later, so let's repeat reset sequence several (3) times.

synaptics_set_advanced_gesture_mode() affect capabilities bits we should
perform comparison after calling this function, otherwise they will never
match and we will be forced to perform full reconnect.

      NFS: NFSv4 readdir loses entries · d1205f87
      Chuck Lever authored 
      
On recent 2.6.38-rc kernels, connectathon basic test 6 fails on
NFSv4 mounts of OpenSolaris with something like:

> ./test6: readdir
> 	./test6: (/mnt/klimt/matisse.test) didn't read expected 'file.12' dir entry, pass 0
> 	./test6: (/mnt/klimt/matisse.test) didn't read expected 'file.82' dir entry, pass 0
> 	./test6: (/mnt/klimt/matisse.test) didn't read expected 'file.164' dir entry, pass 0
> 	./test6: (/mnt/klimt/matisse.test) Test failed with 3 errors
> basic tests failed
> Tests failed, leaving /mnt/klimt mounted
> [cel@matisse cthon04]$

I narrowed the problem down to nfs4_decode_dirent() reporting that the
decode buffer had overflowed while decoding the entries for those
missing files.

verify_attr_len() assumes both it's pointer arguments reside on the
same page.  When these arguments point to locations on two different
pages, verify_attr_len() can report false errors.  This can happen now
that a large NFSv4 readdir result can span pages.

We have reasonably good checking in nfs4_decode_dirent() anyway, so
it should be safe to simply remove the extra checking.

At a guess, this was introduced by commit 6650239a, "NFS: Don't use
vm_map_ram() in readdir".

      NFS: Micro-optimize nfs4_decode_dirent() · c08e76d0
      Chuck Lever authored 
      
Make the decoding of NFSv4 directory entries slightly more efficient
by:

  1.  Avoiding unnecessary byte swapping when checking XDR booleans,
      and

  2.  Not bumping "p" when its value will be immediately replaced by
      xdr_inline_decode()

This commit makes nfs4_decode_dirent() consistent with similar logic
in the other two decode_dirent() functions.

      NFS: Fix an NFS client lockdep issue · e00b8a24
      Trond Myklebust authored 
      
There is no reason to be freeing the delegation cred in the rcu callback,
and doing so is resulting in a lockdep complaint that rpc_credcache_lock
is being called from both softirq and non-softirq contexts.

      xfs: xfs_bmap_add_extent_delay_real should init br_startblock · 24446fc6
      bpm@sgi.com authored 
      
When filling in the middle of a previous delayed allocation in
xfs_bmap_add_extent_delay_real, set br_startblock of the new delay
extent to the right to nullstartblock instead of 0 before inserting
the extent into the ifork (xfs_iext_insert), rather than setting
br_startblock afterward.

Adding the extent into the ifork with br_startblock=0 can lead to
the extent being copied into the btree by xfs_bmap_extent_to_btree
if we happen to convert from extents format to btree format before
updating br_startblock with the correct value.  The unexpected
addition of this delay extent to the btree can cause subsequent
XFS_WANT_CORRUPTED_GOTO filesystem shutdown in several
xfs_bmap_add_extent_delay_real cases where we are converting a delay
extent to real and unexpectedly find an extent already inserted.
For example:

911         case BMAP_LEFT_FILLING:
912                 /*
913                  * Filling in the first part of a previous delayed allocation.
914                  * The left neighbor is not contiguous.
915                  */
916                 trace_xfs_bmap_pre_update(ip, idx, state, _THIS_IP_);
917                 xfs_bmbt_set_startoff(ep, new_endoff);
918                 temp = PREV.br_blockcount - new->br_blockcount;
919                 xfs_bmbt_set_blockcount(ep, temp);
920                 xfs_iext_insert(ip, idx, 1, new, state);
921                 ip->i_df.if_lastex = idx;
922                 ip->i_d.di_nextents++;
923                 if (cur == NULL)
924                         rval = XFS_ILOG_CORE | XFS_ILOG_DEXT;
925                 else {
926                         rval = XFS_ILOG_CORE;
927                         if ((error = xfs_bmbt_lookup_eq(cur, new->br_startoff,
928                                         new->br_startblock, new->br_blockcount,
929                                         &i)))
930                                 goto done;
931                         XFS_WANT_CORRUPTED_GOTO(i == 0, done);

With the bogus extent in the btree we shutdown the filesystem at
931.  The conversion from extents to btree format happens when the
number of extents in the inode increases above ip->i_df.if_ext_max.
xfs_bmap_extent_to_btree copies extents from the ifork into the
btree, ignoring all delalloc extents which are denoted by
br_startblock having some value of nullstartblock.

      xfs: fix dquot shaker deadlock · 0fbca4d1
      Dave Chinner authored 
      
Commit 368e1361 ("xfs: remove duplicate code from dquot reclaim") fails
to unlock the dquot freelist when the number of loop restarts is
exceeded in xfs_qm_dqreclaim_one(). This causes hangs in memory
reclaim.

Rework the loop control logic into an unwind stack that all the
different cases jump into. This means there is only one set of code
that processes the loop exit criteria, and simplifies the unlocking
of all the items from different points in the loop. It also fixes a
double increment of the restart counter from the qi_dqlist_lock
case.
