[PATCH] namei fixes (12/19)
In open_namei() we take mntput(nd->mnt);nd->mnt=path.mnt; out of the if (__follow_mount(...)), making it conditional on nd->mnt != path.mnt instead. Then we shift the result downstream. Equivalent transformations. Signed-off-by: Al Viro <viro@parcelfarce.linux.theplanet.co.uk> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
