From 5787be94725c2229ca9188ce189f872c01c9841f Mon Sep 17 00:00:00 2001 From: Andreas Dilger Date: Wed, 27 Apr 2016 21:37:17 -0400 Subject: [PATCH] staging: lustre: llite: debugging for ll_file_open LASSERT Add debugging for LASSERTF(it_disposition(it, DISP_ENQ_OPEN_REF) in ll_file_open(), since this is a rarely hit failure under racer, and it would be useful to get more information if this is hit again. Print the full intent disposition, as well as the status, in case Oleg's earlier comment about bailing out on any error is actually the case here.
