From f7a2d0688a3b2bb4769402b4c962f54f7b0fc23c Mon Sep 17 00:00:00 2001 From: Xiubo Li Date: Wed, 20 Apr 2022 13:13:02 +0800 Subject: ceph: disable updating the atime since cephfs won't maintain it Since CephFS makes no attempt to maintain atime, we shouldn't try to update it in mmap and generic read cases and ignore updating it in direct and sync read cases. And even we update it in mmap and generic read cases we will drop it and won't sync it to MDS. And we are seeing the atime will be updated and then dropped to the floor again and again.
