[PATCH] namei fixes (7/19)
The first argument of __do_follow_link() switched to struct path * (__do_follow_link(path->dentry, ...) -> __do_follow_link(path, ...)). All callers have the same calls of mntget() right before and dput()/mntput() right after __do_follow_link(); these calls have been moved inside. Obviously equivalent transformations.
