I am getting an Oops when running xfs_fsr. The only way I can get it to

tracing abilities it doesn't look like and xfs problem but I can't reproduce
it anyother way than with xfs_fsr.
I have reliably reproduced the problem on 3 different machines running
2.6.7, 184.108.40.206 (from kernel.org) Most of the rest of the system is fedora
Are you using 4KSTACKS?
If you oops on reiserfs while running xfs userspace, something is going
quite wrong; I'd suspect corruption of some sort - and blowing a stack
might do that. Especially if you've got volume managers under it...
Try turning off CONFIG_4KSTACKS if it's on, and perhaps turn on
CONFIG_DEBUG_STACKOVERFLOW and CONFIG_DEBUG_STACK_USAGE
If you don't have 4kstacks, and you still see overflows, I may have a
patch that will help trim down stack usage during fsr.
