Subject: Re: [PATCH] block: Replace bio_check_ro()'s WARN_ON()
Date: Mon, 25 Nov 2019 09:40:37 -0800	[thread overview]
Message-ID: <20191125174037.GA768@infradead.org> (raw)
In-Reply-To: <201911221131.A34DFAA49@keescook>

So I looked at this a bit, and doing the right thing (TM) will be
a little invase and thus not for 5.5.

But the 5.5. queue already has a patch from Mikulas Patocka:
8b2ded1c94c ("block: don't warn when doing fsync on read-only devices")
which should deal with this issue, and in fact I can't trigger the
WARN_ON with Jens' latest tree.
