Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs
Pull vfs pile #3 from Al Viro:
"Assorted fixes and patches from the last cycle"
* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs:
[regression] chunk lost from bd9b51
vfs: make mounts and mountstats honor root dir like mountinfo does
vfs: cleanup show_mountinfo
init: fix read-write root mount
unfuck binfmt_misc.c (broken by commit e6084d4)
vm_area_operations: kill ->migrate()
new helper: iter_is_iovec()
move_extent_per_page(): get rid of unused w_flags
lustre: get rid of playing with ->fs
btrfs: filp_open() returns ERR_PTR() on failure, not NULL...
