Subject: [PATCH] dax: fix default return code of range_parse()
Date: Tue, 26 Jan 2021 10:13:31 +0800 [thread overview]
Message-ID: <20210126021331.1059933-1-ruansy.fnst@cn.fujitsu.com> (raw)
The return value of range_parse() indicates the size when it is
positive. The error code should be negative.
