Subject: ext4: fix freespace accounting with mballoc on 32bit machines
From: Eric Sandeen <[email protected]>
On a 32bit machine, passing the negative unsigned long fe_len
into percpu_counter_add (which expects s64) messes up the counters:
[root@bear-05 linux-2.6.23-rc7]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sdb7 97G -149P 149P - /mnt/test
Patch below fixes this.
