From 2b2300d62ea413bec631d5b880effa2cc5363acb Mon Sep 17 00:00:00 2001 From: Sage Weil Date: Wed, 9 Jun 2010 16:52:04 -0700 Subject: ceph: try to send partial cap release on cap message on missing inode If we have enough memory to allocate a new cap release message, do so, so that we can send a partial release message immediately. This keeps us from making the MDS wait when the cap release it needs is in a partially full release message. If we fail because of ENOMEM, oh well, they'll just have to wait a bit longer.
