Subject: [PATCH v4 10/17] NFS: Remove racy size manipulations in O_DIRECT
Date: Thu, 23 Jun 2016 16:00:42 -0400 [thread overview]
Message-ID: <1466712049-5326-10-git-send-email-trond.myklebust@primarydata.com> (raw)
In-Reply-To: <1466712049-5326-9-git-send-email-trond.myklebust@primarydata.com>
On success, the RPC callbacks will ensure that we make the appropriate calls
to nfs_writeback_update_inode()
