Subject: [PATCH] 2.6.0: ioctl related warnings in userspace
Date: Thu, 18 Dec 2003 15:43:24 +0100 [thread overview]
Message-ID: <20031218144324.GA15580@convergence.de> (raw)
Hi,
the patch below (2nd resend) removes warnings like:
warning: signed and unsigned type in conditional expression
when compiling userspace applications against a glibc built with 2.6
kernel headers (like on Debian unstable). Please apply.
Regards,
Johannes
