Subject: [lustre-devel] [PATCH 15/29] lustre: lmv: don't include struct lu_qos_rr in client
Date: Sun, 25 Apr 2021 16:08:22 -0400 [thread overview]
Message-ID: <1619381316-7719-16-git-send-email-jsimmons@infradead.org> (raw)
In-Reply-To: <1619381316-7719-1-git-send-email-jsimmons@infradead.org>
From: Mr NeilBrown <neilb@suse.de>
The 'lqrr' field in 'struct lu_qos' is not used on the client (lmv).
So make it server-only for use in lod. We can safely remove it from
the Linux client.
WC-bug-id: https://jira.whamcloud.com/browse/LU-8837
Lustre-commit: b6882c8ae4f47e93 ("LU-8837 lmv: don't include struct lu_qos_rr in client")
