[PATCH] struct path: rename DM's struct path
Rename DM's struct path to struct dm_path to prevent name collision between it and struct path from fs/namei.c. Signed-off-by: Josef "Jeff" Sipek <jsipek@cs.sunysb.edu> Acked-by: Alasdair G Kergon <agk@redhat.com> Cc: <reiserfs-dev@namesys.com> Cc: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
