[2/3] vfs: export vfs_path_lookup()

Commit Message

Miklos Szeredi Oct. 25, 2016, 7:34 a.m. UTC

Exported to modules, but currently residing in fs/internal.h due to commit
197df04c749a ("rename user_path_umountat() to user_path_mountpoint_at()").

Move back to <linux/namei.h> so that overlayfs can make use of it.
