Hi
Patch applied and builds ok.
I created a striped pool with 2x 320GB disks and when i use the pool,
then dmesg will fills up with messages like thous:
zfs_lowmem:2686[0]: 42 EXIT
zfs_lowmem:2681[0]: 42 ENTER
zfs_lowmem:2686[0]: 42 EXIT
zfs_lowmem:2681[0]: 42 ENTER
Also i added zfs_load="YES" to loader.conf and the kernel panics in boot
After power on and loading zfs manualy, i'm was unable to import my
pool.
[root@ofurdolla /home/antab]# zpool import leech
cannot import 'leech': pool may be in use from other system
use '-f' to import anyway
acquiring duplicate lock of same type: "zfs:dbuf"
1st zfs:dbuf @ /usr/src/sys/modules/zfs/../../compat/opensolaris/sys/
mutex.h:44
2nd zfs:dbuf @ /usr/src/sys/modules/zfs/../../compat/opensolaris/sys/
mutex.h:44

-f will force the import and i can use the pool.
Keep up the good work
