df(1) and mount(8) output. This is a bit smilar to OpenSolaris and follows
ZFS route of not listing snapshots by default with 'zfs list' command.
- Add UPDATING entry to note that ZFS snapshots are no longer visible in
mount(8) and df(1) output by default.

by just returning EOPNOTSUPP. This will allow NFS server to fall back to
regular READDIR.
Note that converting inode number to snapshot's vnode is expensive operation.
Snapshots are stored in AVL tree, but based on their names, not inode numbers,
so to convert inode to snapshot vnode we have to interate over all snalshots.
This is not a problem in OpenSolaris, because in their READDIRPLUS
implementation they use VOP_LOOKUP() on d_name, instead of VFS_VGET() on
d_fileno as we do.

where when try to access corrupted directory the kernel will panic.
Until the bug is properly fixed, try to recover from it and log that it

- Be prepared for dbuf to disappear in zfs_reclaim_complete() and check if
z_dbuf field is NULL - this might happen in case of rollback or forced
unmount between zfs_freebsd_reclaim() and zfs_reclaim_complete().
- On forced unmount wait for all znodes to be destroyed - destruction can be
done asynchronously via zfs_reclaim_complete().

Such situation is not supported.
This problem was triggered by something like this:
# zpool create tank da0
# zfs snapshot tank@snap
# cd /tank/.zfs/snapshot/snap (this will mount the snapshot)
# cd
# mount -u nosuid /tank/.zfs/snapshot/snap (refcount leak)
# zpool export tank
cannot export 'tank': pool is busy

we will fail to unmount it, but it won't be removed from the tree,
so in that case there is no need to reinsert it.
This fixes a panic reproducable in the following steps:
# zfs create tank/foo
# zfs snapshot tank/foo@snap
# cd /tank/foo/.zfs/snapshot/snap
# umount /tank/foo
panic: avl_find() succeeded inside avl_add()

(..), calling readdir and looking for previous directory inode. In case of
.zfs/ directory this doesn't work, because .zfs/ is hidden by default, so it
won't be visible in readdir output.
Fix this by implementing VPTOCNP for snapshot directories, so __getcwd()
doesn't fail and getcwd() doesn't have to use readdir method.
This fixes /bin/pwd from within .zfs/snapshot/<name>/.
