Subject: pNFS: Cleanup - do layout segment initialisation in one place
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=119cef97a46e2a4b4fbebcf6655358a0b277732d;p=openwrt%2Fstaging%2Fblogic.git

pNFS: Cleanup - do layout segment initialisation in one place

...instead of splitting the initialisation over init_lseg() and
pnfs_layout_process().
