Subject: [PATCH v2 7/9] pnfs: fix bad error handling in send_layoutget
Date: Wed, 11 May 2016 06:21:12 -0400 [thread overview]
Message-ID: <1462962074-6989-8-git-send-email-jeff.layton@primarydata.com> (raw)
In-Reply-To: <1462962074-6989-1-git-send-email-jeff.layton@primarydata.com>
Currently, the code will clear the fail bit if we get back a fatal
error. I don't think that's correct -- we only want to clear that
bit if the layoutget succeeds.
Fixes: 0bcbf039f6 (nfs: handle request add failure properly)
