2011-12-06 19:42:50.401233 7fc8b1850700 mds.0.locker suppressed and !revoke, skipping client.6143
Importantly, the ifile lock does change state on that inode, but it's always in sync when the attempt to change size fails.

oh, i fixed this a week or two ago. the problem was that the file isn't open read/write, but Client was still trying to set file_max. the mds ignored it (that's why we saw that lock error).
Client now returns -EBADF or something when you try to write to a read-only handle.

Bulk updating project=ceph category=mds bugs so that I can remove the MDS category from the Ceph project to avoid confusion.
