***** SUSPECTED SPAM ***** [PATCH 23/50] xfs: fix issues that cause userspace warnings

[Dave Chinner <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.
