Subject: pNFS: When updating the stateid in layoutreturn, also update the recall range
X-Git-Tag: v4.19~180^2~8
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=ecf8402603d4df1278231439bbe5e92af4e02a17;p=platform%2Fkernel%2Flinux-rpi.git

pNFS: When updating the stateid in layoutreturn, also update the recall range

When we update the layout stateid in nfs4_layoutreturn_refresh_stateid, we
should also update the range in order to let the server know we're actually
returning everything.
