Subject: [PATCH 22/50] libxfs: fix compile warnings
Date: Wed, 19 Jun 2013 15:35:45 +1000	[thread overview]
Message-ID: <1371620173-712-23-git-send-email-david@fromorbit.com> (raw)
In-Reply-To: <1371620173-712-1-git-send-email-david@fromorbit.com>

From: Dave Chinner <dchinner@redhat.com>

Some of the code shared with userspace causes compilation warnings
from things turned off in the kernel code, such as differences in
variable signedness. Fix those issues.

Signed-off-by: Dave Chinner <dchinner@redhat.com>
