Subject: [dpdk-dev] [PATCH v3 1/9] fbarray: fix detach in noshconf mode
Date: Tue,  4 Sep 2018 16:15:42 +0100	[thread overview]
Message-ID: <3ab2d0a7cf61d800e1b4bc8571d79e5a113e0dd7.1536073997.git.anatoly.burakov@intel.com> (raw)
In-Reply-To: <cover.1536073996.git.anatoly.burakov@intel.com>
In-Reply-To: <cover.1536073996.git.anatoly.burakov@intel.com>

In noshconf mode, no shared files are created, but we're still trying
to unlink them, resulting in detach/destroy failure even though it
should have succeeded. Fix it by exiting early in noshconf mode.

Fixes: 3ee2cde248a7 ("fbarray: support --no-shconf mode")
Cc: stable@dpdk.org
