Subject: [PATCH v3 10/13] pnfs: fix bad error handling in send_layoutget
Date: Sat, 14 May 2016 21:06:39 -0400	[thread overview]
Message-ID: <1463274402-17746-11-git-send-email-jeff.layton@primarydata.com> (raw)
In-Reply-To: <1463274402-17746-1-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)
