vfs: fixes and cleanups + add helpers to check r/o bind mounts

And here is the same (well, with some cosmetic fixes) as a git tree, in case it's more convenient for somebody to review/test. git://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/vfs... 7 May 2008 08:31

[PATCH 9/9] Get rid of ipc_lock_down()
[PATCH 09/09] This patch removes the ipc_lock_down() routines: they used to call idr_find() locklessly (given that the ipc ids lock was already held), so they are not needed anymore.
