Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs
Pull third set of VFS updates from Al Viro:
"Misc stuff all over the place. There will be one more pile in a
couple of days"
This is an "evil merge" that also uses the new d_count helper in
fs/configfs/dir.c, missed by commit 84d08fa888e7 ("helper for reading
->d_count")
* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs:
ncpfs: fix error return code in ncp_parse_options()
locks: move file_lock_list to a set of percpu hlist_heads and convert file_lock_lock to an lglock
seq_file: add seq_list_*_percpu helpers
f2fs: fix readdir incorrectness
mode_t whack-a-mole...
lustre: kill the pointless wrapper
helper for reading ->d_count
