From 5c97f5de2c7cd9e2a5f71bc7c53125d9a2833ca9 Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Mon, 4 Jan 2016 11:53:04 -0500 Subject: NFSv4.1/pNFS: pnfs_mark_matching_lsegs_return() should set the iomode If pnfs_mark_matching_lsegs_return() needs to mark a layout segment for return, then it must also set the return iomode.
