Subject: [PATCH 01/13] libfrog: fix workqueue error communication problems
Date: Mon, 26 Aug 2019 14:28:24 -0700	[thread overview]
Message-ID: <156685490445.2841546.18161974605479380089.stgit@magnolia> (raw)
In-Reply-To: <156685489821.2841546.10616502094098044568.stgit@magnolia>

From: Darrick J. Wong <darrick.wong@oracle.com>

Convert all the workqueue functions to return positive error codes so
that we can move away from the libc-style indirect errno handling and
towards passing error codes directly back to callers.
