Subject: [PATCH v8 02/20] xfs: Check for -ENOATTR or -EEXIST
Date: Fri,  3 Apr 2020 15:12:11 -0700	[thread overview]
Message-ID: <20200403221229.4995-3-allison.henderson@oracle.com> (raw)
In-Reply-To: <20200403221229.4995-1-allison.henderson@oracle.com>

Delayed operations cannot return error codes.  So we must check for
these conditions first before starting set or remove operations
