Subject: Re: [PATCH] raceless request_region() fix (was Re: Linux 2.6.0-test4)
Date: Mon, 25 Aug 2003 17:59:20 -0400 [thread overview]
Message-ID: <3F4A86B8.9080404@pobox.com> (raw)
In-Reply-To: <200308260026.47994.insecure@mail.od.ua>
Is it a race if noone cares? :)
The code does
if (!request_region(...))
fail
touch hardware
release_region
if (!request_region(...))
fail
If the HIGHLY UNLIKELY event of another ISA driver claiming this region
occurs, the system continues working just fine.
At the time, I was thinking that any further touching of the code should
be converting it to a more pnp-like structure.
Jeff
