From 560671a0d3c9ad2d647fa6d09375a262e1f19c4f Mon Sep 17 00:00:00 2001 From: "Aneesh Kumar K.V" Date: Mon, 5 Jan 2009 22:20:24 -0500 Subject: ext4: Use high 16 bits of the block group descriptor's free counts fields Rename the lower bits with suffix _lo and add helper to access the values. Also rename bg_itable_unused_hi to bg_pad as in e2fsprogs.
