From 04d000eb358919043da538f197d63f2a5924a525 Mon Sep 17 00:00:00 2001 From: Sage Weil Date: Fri, 7 May 2010 11:26:34 -0700 Subject: [PATCH] ceph: fix open file counting on snapped inodes when mds returns no caps It's possible the MDS will not issue caps on a snapped inode, in which case an open request may not __ceph_get_fmode(), botching the open file counting. (This is actually a server bug, but the client shouldn't BUG out in this case.)
