Hi,
Gave xfs a test spin today. It survived a fair amount of abuse, before
crashing on umount. Here's the oops:

Looks like it tried to grab a spin lock in use and got caught by
the nmi watchdog.
In addition, this showed up when the partition was full:
xfs_iomap_write returning ERROR 28
write, delalloc. add some code here
