Subject: [PATCH v3 0/6] ceph: don't request caps for idle open files
Date: Fri, 28 Feb 2020 19:55:44 +0800 [thread overview]
Message-ID: <20200228115550.6904-1-zyan@redhat.com> (raw)
This series make cephfs client not request caps for open files that
idle for a long time. For the case that one active client and multiple
standby clients open the same file, this increase the possibility that
mds issues exclusive caps to the active client.
Yan, Zheng (4):
ceph: always renew caps if mds_wanted is insufficient
ceph: consider inode's last read/write when calculating wanted caps
ceph: simplify calling of ceph_get_fmode()
ceph: remove delay check logic from ceph_check_caps()
