btrfs io errors on 3.4rc1

[Dave Jones <davej@redhat.com>]

Updated to rc1 this morning, and my machines with btrfs are all freaking out..

I got this from my cron email ..

/etc/cron.daily/prelink: line 41: /var/lib/prelink/full: Input/output error
cp: cannot create regular file `/var/lib/prelink/quick': Input/output error
/etc/cron.daily/prelink: line 45: /var/log/prelink/prelink.log: Input/output error

I tried updating my git tree..

$ gp
error: cannot open .git/FETCH_HEAD: Input/output error

fatal: fsync error on '.git/objects/pack/tmp_pack_gq3edw': Input/output error

I looked in dmesg, nothing out of the ordinary (disks dying etc -- plus it's happening
on two machines, so unlikely they both have hardware problems)

But anything that does writes seems to have serious issues..

$ fsx foo

ftruncate1: 2e52c
dotruncate: ftruncate: Input/output error

tried to send this email..

collect: Cannot write ./dfq32HpM1C010652 (fsync, uid=1000, gid=51): Input/output error

3.3 is fine.
