Revision 6719db6a23d4b7f1e5052eedae394135e3aef9c1 authored by Josef Bacik on 20 August 2011, 12:29:51 UTC, committed by Linus Torvalds on 21 August 2011, 14:02:00 UTC
This fixes a regression introduced by commit cdcb725c05fe ("Btrfs: check
if there is enough space for balancing smarter").  We can't do 64-bit
divides on 32-bit architectures.

In cases where we need to divide/multiply by 2 we should just left/right
shift respectively, and in cases where theres N number of devices use
do_div.  Also make the counters u64 to match up with rw_devices.
Thanks,
