From d28e75bb79a66f829ddcdea413f8849290793dae Mon Sep 17 00:00:00 2001 From: Xiubo Li Date: Mon, 11 Apr 2022 09:59:09 +0800 Subject: [PATCH] ceph: fix statx AT_STATX_DONT_SYNC vs AT_STATX_FORCE_SYNC check From the posix and the initial statx supporting commit comments, the AT_STATX_DONT_SYNC is a lightweight stat and the AT_STATX_FORCE_SYNC is a heaverweight one. And also checked all the other current usage about these two flags they are all doing the same, that is only when the AT_STATX_FORCE_SYNC is not set and the AT_STATX_DONT_SYNC is set will they skip sync retriving the attributes from storage.
