From ebcee4b5c9136096f64ee6f691a013d7c0a4bc34 Mon Sep 17 00:00:00 2001 From: Mark Fasheh Date: Mon, 28 Jul 2008 14:55:20 -0700 Subject: ocfs2: Track local alloc bits internally Do this instead of tracking absolute local alloc size. This avoids needless re-calculatiion of bits from bytes in localalloc.c. Additionally, the value is now in a more natural unit for internal file system bitmap work.
