Merge branch 'work.mount-base' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs
Pull vfs mount API infrastructure updates from Al Viro:
"Infrastructure bits of mount API conversions.
The rest is more of per-filesystem updates and that will happen
in separate pull requests"
* 'work.mount-base' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs:
mtd: Provide fs_context-aware mount_mtd() replacement
vfs: Create fs_context-aware mount_bdev() replacement
new helper: get_tree_keyed()
vfs: set fs_context::user_ns for reconfigure
