The following reply was made to PR kern/46990; it has been noted by GNATS.

From: "Taylor R Campbell" <>
Subject: PR/46990 CVS commit: src/sys/fs/tmpfs
Date: Tue, 25 Sep 2012 16:11:42 +0000

 Module Name:   src
 Committed By:  riastradh
 Date:          Tue Sep 25 16:11:42 UTC 2012
 Modified Files:
        src/sys/fs/tmpfs: tmpfs_rename.c
 Log Message:
 Check tmpfs_rmdired_p after tmpfs_vnode_get when walking up the tree.
 tmpfs_vnode_get drops all locks except possibly the reclaiming bit
 lock to keep the tmpfs node from being reclaimed while we're still
 interested in it.  Consequently, it does not keep the directory's
 existence invariant, so we must check that after tmpfs_vnode_get.
 Fixes PR kern/46990.  Tested by Wolfgang Stukenbrock.
