Subject: pNFS: Always update the layout stateid if NFS_LAYOUT_INVALID_STID is set
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=13bede18de41e2cfe8f67c1cd8b6d10be42ef473;p=openwrt%2Fstaging%2Fblogic.git

pNFS: Always update the layout stateid if NFS_LAYOUT_INVALID_STID is set

If the layout stateid is invalid, then pnfs_set_layout_stateid() must
always initialise it.
