Subject: [PATCH 05/12] statx: don't clear STATX_ATIME on SB_RDONLY
Date: Thu, 28 Nov 2019 16:59:33 +0100	[thread overview]
Message-ID: <20191128155940.17530-6-mszeredi@redhat.com> (raw)
In-Reply-To: <20191128155940.17530-1-mszeredi@redhat.com>

IS_NOATIME(inode) is defined as __IS_FLG(inode, SB_RDONLY|SB_NOATIME), so
generic_fillattr() will clear STATX_ATIME from the result_mask if the super
block is marked read only.

This was probably not the intention, so fix to only clear STATX_ATIME if
the fs doesn't support atime at all.
