Subject: Re: [PATCH v2 1/2] loop: Report EOPNOTSUPP properly
Date: Wed, 13 Feb 2019 21:31:54 -0500 [thread overview]
Message-ID: <yq1h8d7qew5.fsf@oracle.com> (raw)
In-Reply-To: <20190207205730.199332-2-evgreen@chromium.org> (Evan Green's message of "Thu, 7 Feb 2019 12:57:28 -0800")
Evan,
> Properly plumb out EOPNOTSUPP from loop driver operations, which may
> get returned when for instance a discard operation is attempted but
> not supported by the underlying block device. Before this change,
> everything was reported in the log as an I/O error, which is scary and
> not helpful in debugging.
