KERNCONF files silently failed giving no indication as to why, only to
subsequently discover during installkernel that the desired kernel was

- Update aio_return/waitcomplete wrappers for the ssize_t return type.
- Fix the aio_return() wrapper to fail with EINVAL on a pending job.
This matches the semantics of the in-kernel system call. Also,
aio_return() returns errors via errno, not via the return value.

Similar to #6334, but this time with empty directories:
$ zfs create tank/quota
$ zfs set quota=10M tank/quota
$ zfs snapshot tank/quota@snap1
$ zfs set mountpoint=/mnt/tank/quota tank/quota
$ mkdir /mnt/tank/quota/dir # create an empty directory
$ mkfile 11M /mnt/tank/quota/11M
/mnt/tank/quota/11M: initialized 9830400 of 11534336 bytes: Disc quota exceeded
$ rmdir /mnt/tank/quota/dir # now unlink the empty directory
rmdir: directory "/mnt/tank/quota/dir": Disc quota exceeded
From user perspective, I would expect that ZFS is always able to remove files
and directories even when the quota is exceeded.

If a ZFS object contains a hole at level one, and then a data block is created
at level 0 underneath that l1 block, l0 holes will be created. However, these
l0 holes do not have the birth time property set; as a result, incremental
sends will not send those holes.
Fix is to modify the dbuf_read code to fill in birth time data.

dnode_next_offset is used in a variety of places to iterate over the holes or
allocated blocks in a dnode. It operates under the premise that it can iterate
over the blockpointers of a dnode in open context while holding only the
dn_struct_rwlock as reader. Unfortunately, this premise does not hold.
When we create the zio for a dbuf, we pass in the actual block pointer in the
indirect block above that dbuf. When we later zero the bp in
zio_write_compress, we are directly modifying the bp. The state of the bp is
now inconsistent from the perspective of dnode_next_offset: the bp will appear
to be a hole until zio_dva_allocate finally finishes filling it in. In the
meantime, dnode_next_offset can detect a hole in the dnode when none exists.
I was able to experimentally demonstrate this behavior with the following
setup:
1. Create a file with 1 million dbufs.
2. Create a thread that randomly dirties L2 blocks by writing to the first L0
block under them.
3. Observe dnode_next_offset, waiting for it to skip over a hole in the middle
of a file.
4. Do dnode_next_offset in a loop until we skip over such a non-existent hole.
The fix is to ensure that it is valid to iterate over the indirect blocks in a
dnode while holding the dn_struct_rwlock by passing the zio a copy of the BP
and updating the actual BP in dbuf_write_ready while holding the lock.

It is not safe to iterate the sub-channel list w/o lock on the

and iterate the sub-channel list. We leverage the
