From f4c753b7eacc277e506066abdda351cbc1cf8e6a Mon Sep 17 00:00:00 2001 From: Paul Menage Date: Tue, 29 Apr 2008 00:59:56 -0700 Subject: [PATCH] CGroup API files: rename read/write_uint methods to read_write_u64 Several people have justifiably complained that the "_uint" suffix is inappropriate for functions that handle u64 values, so this patch just renames all these functions and their users to have the suffic _u64.
