linux-next: manual merge of the akpm tree with Linus' tree

Hi Andrew,

Today's linux-next merge of the akpm tree got a conflict in fs/dcache.c
between commit 8aab6a27332b ("vfs: reorganize dput() memory accesses")
from Linus' tree and commit "dentry: move to per-sb LRU locks" from the
akpm tree.

I fixed it up (I think - see below) and can carry the fix as necessary
(no action is required).
