Subject: Re: [PATCH v2 01/12] get rid of unlikely() on page_copy_sane() calls
Date: Sun, 30 Oct 2022 01:12:56 -0700 [thread overview]
Message-ID: <Y14yCDdhW/QGOp+l@infradead.org> (raw)
In-Reply-To: <20221028023352.3532080-1-viro@zeniv.linux.org.uk>
This could explain why your are dropping the unlikely, 'cause just
from the page this is non-obvious. Especially as the patch seems to
do a lot more than just removing an unlikely.
