The operation is keyed off a new inode flag (S_AUTOMOUNT). This makes it easier to add an AT_ flag to suppress terminal segment automount during pathwalk. It should also remove the need for the kludge code in the pathwalk algorithm to handle directories with follow_link() semantics. I've only changed __follow_mount() to handle automount points, but it might be necessary to change follow_mount() too. The latter is only used from follow_dotdot(), but any automounts on ".." should be pinned whilst we're using a child of it. Note that autofs4's use of follow_mount() will need examining if this patch is committed.
