Subject: [PATCH v8 15/20] fs: ceph: Initialize filesystem timestamp ranges
Date: Sun, 18 Aug 2019 09:58:12 -0700 [thread overview]
Message-ID: <20190818165817.32634-16-deepa.kernel@gmail.com> (raw)
In-Reply-To: <20190818165817.32634-1-deepa.kernel@gmail.com>
Fill in the appropriate limits to avoid inconsistencies
in the vfs cached inode times when timestamps are
outside the permitted range.
According to the disscussion in
https://patchwork.kernel.org/patch/8308691/ we agreed to use
unsigned 32 bit timestamps on ceph.
Update the limits accordingly.
