hi,
is the following calltrace related to xfs or something else?
it happended during "stress --hdd 20 --hdd-bytes 2g" on a
raid10 volume:
> # cat /proc/mdstat
> Personalities : [raid1] [raid10]
> md0 : active raid10 sdd5[3] sdc5[2] sdb5[1] sda5[0]
> 39069824 blocks 64K chunks 2 near-copies [4/4] [UUUU]
maybe this is xfs' way to tell "out of diskspace"? :)
