* zpool cannot be destroyed -> could not destroy 'test': could not unmount datasets
We are leaking descriptor after open -> I'm getting EBUSY from spscfs_open.
2) ZPL part
* test zfs_vfsops.c and zfs_vnops.c changes
* xattr and acl support is needed for filesystem permisions ?
* Check if we are calling vfs_option clear set routines from vfs.c with mnt_updating lock held.
* Port zfs_replay.c -> DONE
3) ZFS part
* ACL support, xattr calls support
* Snapshots support
* iSCSI targets support
* NFSv3, NFSv4 support
* Samba filesystem support
* Implement getpages/putpages for zfs, can be done with genfs_* routines but vnode_t need some changes.
* zfs_rename support, Working but there are some issues with LOCKDEBUG see comment above zfs_rename.
NetBSD ZFS Integration TODO
Pre-integration tasks.
DONE why is zfs module deadlocking.
DONE try to create a zvol/pool.
DONE when creating zvol/pool ok, do minor stress testing.
DONE port vfsops and vnodeops. ignore getpages/putpages.
DONE lookupname/lookupnameat/nameiat
DONE device properties for disk partitions.
DONE changes to newfs fsck for zvols.
DONE re-read zpool.cache and reconfigure pools.
DONE successful unload of the module.
DONE implement basic getpages/putpages.
DONE callbacks into arc, for reclaim of memory or kernel virual space.
DONE prevent module loading if less than 512MB RAM.
- maybe changing the order of arguments for pool_cache constructors.
DONE check ioctl handlers for safety (for patch to allow old-style unix ioctl)
PDONE port ZFS ACL stuff, enough for POSIX.
DONE port zfs_replay.c to NetBSD
DONE successfully compile a kernel.
- stress testing.
DONE rc.d integration for zfs.
DONE fix dangling vnode panic, get zfs unmount to work
DONE fix zfs_rename bug -> fix should be sent back to sun
DONE syncer/atime issues
Post-integration tasks.
- device properties for unique device id (driver:model-revision-serial-etc).
- use device id to locate disks/partitions
PDONE port ZFS snapshot / ctldir stuff.
- zfs/nfs integration.
- zfs/iscsi integration.
- native getpages/putpages.
PDONE zfs v22 update ZFS to latest.
- Implement *at syscalls correctly.
Pre netbsd-6.0 tasks
- More testing especially zvol, vdev and zfs code snapshot will stay disabled
- Get ztest and zdb working
- Get zfs properties working
Post netbsd-6.0 tasks
- Update to latest version
- Harden zfs, test, survive build.sh on zfs
- all Post integration tasks
- Write regression test suite
- RUMP port (might be very good idea.)

## List of Know ZFS bugs/issues
#######
User-land
=========
1) zpool list ENOMEM error .... fixed in rev 1.3 sunddi.h and rev 1.5 zfs_ioctl.h
2) zfs unmount crash in getmntinfo
3) ztest TXG dmu commit threshold problem ?? Maybe fixed by replacing atomic functions with mutex.
4) ztest vdev resize problem (spa_thread ? )
Kernel
======
1) Faulted zpool after modload (missing ztest/ dmu_objset)
ZDB fails to work with because of this problem. This need to be investigated more.
see zdb.c#2904
2) data lost on filesystem after panic
3) Strange panic during zfs_znode_dmu_init
4) zpool scrub panic in vdev_open->vdev_disk_open->VOP_IOCTL
5) zfs set doesn't work -> zfs set dedup=on, zfs set compression=gzip
6) device nodes in /dev/zvol are not created
