From: Andreas Dilger Date: Thu, 28 Apr 2016 01:37:17 +0000 (-0400) Subject: staging: lustre: llite: debugging for ll_file_open LASSERT X-Git-Tag: v4.7-rc1~90^2~304 X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=5787be94725c2229ca9188ce189f872c01c9841f;p=karo-tx-linux.git 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.
