[PATCH 19/19] xfs: convert directory vector functions to constants

Dave Chinner
2013-10-14T22:18:24Z

From: Dave Chinner <dchinner@redhat.com>

Many of the vectorised function calls now take no parameters and
return a constant value. There is no reason for these to be vectored
functions, so convert them to constants

Binary sizes:
