From 021b65bb1e4e4b625c80bbb82651e5e155721ef3 Mon Sep 17 00:00:00 2001 From: Theodore Ts'o Date: Fri, 9 Sep 2011 19:08:51 -0400 Subject: ext4: Rename ext4_free_blks_{count,set}() to refer to clusters The field bg_free_blocks_count_{lo,high} in the block group descriptor has been repurposed to hold the number of free clusters for bigalloc functions. So rename the functions so it makes it easier to read and audit the block allocation and block freeing code. Note: at this point in bigalloc development we doesn't support online resize, so this also makes it really obvious all of the places we need to fix up to add support for online resize.
