Description

While running fsstress on HAMMER on a build of DragonFly from today (after the
most recent dsched fixes, with fq policy), I got a panic in
hammer_setup_child_callback, called from hammer_rec_rb_tree_RB_SCAN, ultimately
from hammer_flusher_slave_thread. Fsync_mode = 2.

Core at http://acm.jhu.edu/~me/vmcore.n0.gz, kernel at

Hi,

I am unsure whether this is an issue with fq or hammer itself.
We would need to run fsstress again and see if it can be reproduced.

Cheers,
Antonio Huete
