4.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jeff Layton <jlayton@xxxxxxxxxx>
commit 6df8c9d80a27cb587f61b4f06b57e248d8bc3f86 upstream.
sparse says:
fs/ceph/mds_client.c:291:23: warning: restricted __le32 degrades to integer
fs/ceph/mds_client.c:293:28: warning: restricted __le32 degrades to integer
fs/ceph/mds_client.c:294:28: warning: restricted __le32 degrades to integer
fs/ceph/mds_client.c:296:28: warning: restricted __le32 degrades to integer
The op value is __le32, so we need to convert it before comparing it.
