From 9280be24dc9c7aaee230de3ed33f8357386de9a2 Mon Sep 17 00:00:00 2001 From: "Yan, Zheng" Date: Tue, 14 Oct 2014 10:33:35 +0800 Subject: [PATCH] ceph: fix file lock interruption When a lock operation is interrupted, current code sends a unlock request to MDS to undo the lock operation. This method does not work as expected because the unlock request can drop locks that have already been acquired. The fix is use the newly introduced CEPH_LOCK_FCNTL_INTR/CEPH_LOCK_FLOCK_INTR requests to interrupt blocked file lock request. These requests do not drop locks that have alread been acquired, they only interrupt blocked file lock request. Signed-off-by: Yan, Zheng --- Reading git-format-patch failed
