  autofs4 - remove autofs4_lock
  autofs4 - fix d_manage() return on rcu-walk
  autofs4 - fix autofs4_expire_indirect() traversal

  vfs - check non-mountpoint dentry might block in __follow_mount_rcu()
  ...

NOTE!

This merge commit was created to fix compilation error. The block
tree was merged upstream and removed the 'elv_queue_empty()'
function which the new 'mtdswap' driver is using. So a simple
merge of the mtd tree with upstream does not compile. And the
mtd tree has already be published, so re-basing it is not an option.

To fix this unfortunate situation, I had to merge upstream into the
mtd-2.6.git tree without committing, put the fixup patch on top of
this, and then commit this. The result is that we do not have commits
which do not compile.

In other words, this merge commit "merges" 3 things: the MTD tree, the
upstream tree, and the fixup patch.

help
Drivers may select this option to force specific constant
values for parameters 'm' (Galois field order) and 't'
(error correction capability). Those specific values must
be set by declaring default values for symbols BCH_CONST_M
and BCH_CONST_T.
Doing so will enable extra compiler optimizations,
improving encoding and decoding performance up to 2x for
usual (m,t) values (typically such that m*t < 200).
When this option is selected, the BCH library supports
only a single (m,t) configuration. This is mainly useful
for NAND flash board drivers requiring known, fixed BCH
parameters.
config BCH_CONST_M

help
Constant value for Galois field order 'm'. If 'k' is the
number of data bits to protect, 'm' should be chosen such
that (k + m*t) <= 2**m - 1.
Drivers should declare a default value for this symbol if
they select option BCH_CONST_PARAMS.
