There seems to be a annoying problem using NFSv4 to access ZFS
file systems under certain circumstances. It's easily reproduced:
nfs_client1: mount server:/export /mnt
nfs_client1: cd /mnt
nfs_client1: echo foo >junk
nfs_client1: cat junk
foo
Now on a different NFSv4 client:
nfs_client2: mount server:/export /mnt
nfs_client2: cd /mnt
nfs_client2: vi junk
# Make some changes to /mnt/junk and save
# This change the inode associated with /mnt/junk
Now back to the original client:
nfs_client1: cat junk
cat: junk: No such file or directory
Admittedly NFSv4 is not advertised as a cluster file system that
maintains a completely coherent view of data across multiple nodes.
But it does have some mechanisms built in that try to deal with
situations like the above. Namely, it employs specialized file
handle lookup routines that return ESTALE when a file handle contains
a non-existant inode value. The ESTALE return triggers a return
full file path lookup from the client to determine if the file has
actually gone away or if the cached file handle is no longer valid.
ZFS behavior can be brought into line with other file systems
(e.g., ext4) by applying the following patch:

Per the documentation for dnode_next_offset in dnode.c, the "txg"
parameter specifies a lower bound on which transaction the dnode can
be found in. We are interested in all dnodes that are removed between
the first and last transaction in the snapshot. It doesn't need to be
created in that snapshot to correspond to a removed file.
In fact, the behavior of zfs diff in the test case exactly matches
this: the transaction that created the data that was deleted in snapshot
"2" was produced before, in snapshot "1", definitely predating the first
transaction in snapshot "2".

When ASSERTs are compiled out by using the --disable-debug configure
option. Then the local variable 'dsl_pool_t *dp' will be unused and
generate a compiler warning. Since this variable is only used once
in the ASSERT replace it with 'ds->ds_dir->dd_pool'.
This has the additional advantage of potentially saving a few bytes
on the stack depending on how gcc decides to compile the function.
This issue was not noticed immediately because the automated builders
use --enable-debug to make the testing as rigorous as possible.

This commit updates the copyright boilerplate within the ZED subtree.
The instructions for appending a contributor copyright line have
been removed. Manually maintaining copyright notices in this
manner is error-prone, imprecise at a file-scope granularity, and
oftentimes inaccurate. These lines can become a pernicious source of
merge conflicts. A commit log is better suited to maintaining this
information. Consequently, a line has been added to the boilerplate
to refer to the git commit log for authoritative copyright attribution.
To account for the scenario where a file may become separated from
the codebase and commit history (i.e., it is copied somewhere else),
a line has been added to identify the file's origin.

Porting Notes:
* Included in this patch is a tiny ISP2() cleanup in zio_init() from
Illumos 5255.
* Unlike the upstream Illumos commit this patch does not impose an
arbitrary 128K block size limit on volumes. Volumes, like filesystems,
are limited by the zfs_max_recordsize=1M module option.
* By default the maximum record size is limited to 1M by the module
option zfs_max_recordsize. This value may be safely increased up to
16M which is the largest block size supported by the on-disk format.
At the moment, 1M blocks clearly offer a significant performance
improvement but the benefits of going beyond this for the majority
of workloads are less clear.
* The illumos version of this patch increased DMU_MAX_ACCESS to 32M.
This was determined not to be large enough when using 16M blocks
because the zfs_make_xattrdir() function will fail (EFBIG) when
assigning a TX. This was immediately observed under Linux because
all newly created files must have a security xattr created and
that was failing. Therefore, we've set DMU_MAX_ACCESS to 64M.
* On 32-bit platforms a hard limit of 1M is set for blocks due
to the limited virtual address space. We should be able to relax
this one the ABD patches are merged.

The umem_alloc_aligned() function should not assume that a 'void *'
type is 64-bit. It will not be on 32-bit platforms. Rather than
complicating the ASSERT to handle this it is simply removed.
Additionally, the '%lu' format specifier should not be assumed to
imply a 64-bit value. Fix this by using the 'llu' format specifier
which will always be atleast 64-bit and explicitly casing the
variable to an u_longlong_t. This issue is handled the same way
in many other parts of the code.

It's been reported that threads would loop infinitely inside zfs_zget. The
speculated cause for this is that if an inode is marked for evict, zfs_zget
would see that and loop. However, if the looping thread doesn't yield, the
inode may not have a chance to finish evict, thus causing a infinite loop.
This patch solve this issue by add cond_resched to zfs_zget, making the
looping thread to yield when needed.
