            Bug ID: 1488909
           Summary: Fix the type of 'len' in posix.c, clang is showing a
                    warning
           Product: GlusterFS
           Version: mainline
         Component: build
          Assignee: bugs at gluster.org
          Reporter: mscherer at redhat.com
                CC: bugs at gluster.org



Description of problem:

Building with clang show this warning:

posix.c:133:17: warning: comparison of unsigned expression < 0 is always false
[-Wtautological-compare]

Looking at the code, the problem is that we compare len, a unsigned type to see
if that's < 0, which doesn't make sense.
