From bf73c62e7ff8dc220f3f57df4e42f9947320c447 Mon Sep 17 00:00:00 2001 From: "Yan, Zheng" Date: Thu, 5 Mar 2020 20:21:04 +0800 Subject: ceph: check all mds' caps after page writeback If an inode has caps from multiple mds's, the following can happen: - non-auth mds revokes Fsc. Fcb is used, so page writeback is queued. - when writeback finishes, ceph_check_caps() is called with auth only flag. ceph_check_caps() invalidates pagecache, but skips checking any non-auth caps.
