When truncating the inode we will just set the ifile lock state to LOCK_XLOCKSNAP and then try to revoke the 'Fb' caps, but if the client couldn't release the 'Fb' cap in time just replies with a normal cap updating request, the MDS will successfully transfer the ifile's lock state to LOCK_EXCL, which is stable. That means the MDS will wake up the truncating request and continue truncating the objects from Rados without waiting the clients to flush the diry buffer. Fixes: commit 9c65920 ("mds: force client flush snap data before truncating objects") Fixes: https://tracker.ceph.com/issues/62580 Signed-off-by: Xiubo Li <xiubli@redhat.com> (cherry picked from commit 68179ae)
