Date: Fri, 06 Jul 2007 18:08:23 +0200 [thread overview]
Message-ID: <468E68F7.8070005@bellard.org> (raw)
In-Reply-To: <Pine.LNX.4.64.0707061111150.12799@trantor.stuart.netsweng.com>
Please update page_check_range() (and other related functions) to return
-EFAULT instead of EFAULT in case of error.
Moreover, I believe using similar functions as Linux for memory access
(copyfromuser, copytouser, get_user, put_user) would be cleaner.
Regards,
Fabrice.
