Subject: [lustre-devel] [PATCH 14/27] lustre: llite: Return errors for aio
Date: Sun, 13 Jun 2021 19:11:24 -0400	[thread overview]
Message-ID: <1623625897-17706-15-git-send-email-jsimmons@infradead.org> (raw)
In-Reply-To: <1623625897-17706-1-git-send-email-jsimmons@infradead.org>

From: Patrick Farrell <farr0186@gmail.com>

The aio code incorrectly discards errors from
ll_direct_rw_pages.  Fix this and add a test for this.
