I fixed a few SUJ bugs. If those of you who reported one of the

I've started seeing a panic "Sleeping thread owns a non-sleepable lock",
though it seems to be occurring both with and without journaling. The
back trace when journaling is disabled is:
Can you tell me what the lock is? This may be related to recent vm work
which went in at the same time.
sched_switch
mi_switch
sleepq_wait
_sleep
bwait
bufwait
bufwrite
ffs_balloc_ufs2
ffs_write
VOP_WRITE_APV
vnode_pager_generic_putpages
VOP_PUTPAGES
vnode_pager_putpages
vm_pageout_flush
vm_object_page_collect_flush
vm_object_page_clean
vfs_msync
sync_fsync
VOP_FSYNC_APV
sync_vnode
sched_sync
fork_exit
fork_trampoline
I've also noticed that since disabling journaling a full fsck seems to
be occurring on boot; background fsck seems to have been disabled.
When you disable journaling it also disables soft-updates. You need to
re-enable it. I could decouple this. It's hard to say which is the POLA.
Thanks,
Jeff
