[PATCH] r/o bind mounts: get callers of vfs_mknod/create/mkdir()
This takes care of all of the direct callers of vfs_mknod(). Since a few of these cases also handle normal file creation as well, this also covers some calls to vfs_create(). So that we don't have to make three mnt_want/drop_write() calls inside of the switch statement, we move some of its logic outside of the switch and into a helper function suggested by Christoph. This also encapsulates a fix for mknod(S_IFREG) that Miklos found.
