Subjectlinux-next: manual merge of the fsnotify tree with Linus' tree
Hi Eric,

Today's linux-next merge of the fsnotify tree got a conflict in
fs/notify/fsnotify.c between commit
4d4eb36679adbdd75495e1bbfe7ac40e4ae41dea ("fsnotify: use dget_parent")
from Linus' tree and commit b14be22c572d5d98e2ffebf63e2d1aa1f088875b
("fsnotify: call fsnotify_parent in perm events") from the fsnotify tree.

Just context changes. I fixed it up (see below) and can carry the fix as
necessary.

Cheers,
