Fix NFS sticky bit permission denied error
When zfs_sticky_remove_access() was originally adapted for Linux
a typo was made which altered the intended behavior.  As described
in the block comment, the intended behavior is that permission
should be granted when the entry is a regular file and you have
write access.  That is, S_ISREG should have been used instead of
S_ISDIR.

Restricting permission to regular files made good sense for older
systems where setting the bit on executable files would instruct
the system to save the program's text segment on the swap device.

On modern systems this behavior has been replaced by the sticky
bit acting as a restricted deletion flag and the plain file
restriction has been relaxed.

Fix 'zpool create|add' replication level check
When the pool configuration contains a hole due to a previous device
removal ignore this top level vdev.  Failure to do so will result in
the current configuration being assessed to have a non-uniform
replication level and the expected warning will be disabled.

The zpool_add_010_pos test case was extended to cover this scenario.

Preserve itx alloc size for zio_data_buf_free()
Using zio_data_buf_alloc() to allocate the itx's may be unsafe
because the itx->itx_lr.lrc_reclen field is not constant from
allocation to free.  Using a different itx->itx_lr.lrc_reclen
size in zio_data_buf_free() can result in the allocation being
returned to the wrong kmem cache.

This issue can be avoided entirely by storing the allocation size
in itx->itx_size and using that for zio_data_buf_free().

48ac22d855 initramfs: Honor canmount=off
The initramfs script was not honoring canmount=off.  With this change,
it does.  If the administrator has asked that a filesystem not be
mounted, that should be honored.

As an exception, the initramfs script ignores canmount=off on the
rootfs.  The rootfs should not have canmount=off set either.  However,
mounting it anyway seems harmless because it is being asked for
explicitly.  The point of this exception is to avoid the risk of
breaking existing systems, just in case someone has canmount=off set on
their rootfs.

The initramfs still mounts filesystems with canmount=noauto.  This is
necessary because it is typical to set that on the rootfs so that it can
be cloned.  Without canmount=noauto, the clones' duplicate mountpoints
would conflict.

This is the remainder of the fix for:

bd2958dea0 initramfs: Honor mountpoint=none/legacy
For filesystems that are children of the rootfs, when mountpoint=none or
mountpoint=legacy, the initrafms script would assume a mountpoint based
on the dataset path.  Given that the rootfs should have mountpoint=/ and
mountpoint inheritance is is the default behavior of ZFS, this behavior
seems unnecessary.  In any event, it turns mountpoint=none into a no-op.
That removes this option from the administrator, and if someone uses it,
it does not work as expected.  Worse yet, if the mountpoint directory
does not exist (which is the typical case for mountpoint=none), the
mounting and thus the boot process will fail.  For the case of
mountpoint=legacy, the assumed mountpoint may not be the correct value
set in /etc/fstab.

This change makes the initramfs script not mount the filesystem in
either case.  For mountpoint=none, this means we are correctly honoring
the setting.  For mountpoint=legacy, there are two scenarios:  If
canmount=on, the filesystem will be mounted by the normal mechanisms
later in the boot process.  If canmount=noauto, the filesystem will not
be mounted at all, unless the administrator has done something special.
If they're not doing something special and they want it mounted by the
initramfs, they can simply not set mountpoint=legacy.

This is part of the fix for:

d4a72f2386 Sequential scrub and resilvers
Currently, scrubs and resilvers can take an extremely
long time to complete. This is largely due to the fact
that zfs scans process pools in logical order, as
determined by each block's bookmark. This makes sense
from a simplicity perspective, but blocks in zfs are
often scattered randomly across disks, particularly
due to zfs's copy-on-write mechanisms.

This patch improves performance by splitting scrubs
and resilvers into a metadata scanning phase and an IO
issuing phase. The metadata scan reads through the
structure of the pool and gathers an in-memory queue
of I/Os, sorted by size and offset on disk. The issuing
phase will then issue the scrub I/Os as sequentially as
possible, greatly improving performance.

This patch also updates and cleans up some of the scan
code which has not been updated in several years.

99834d1950 Fix truncate(2) mtime and ctime handling
On Linux, ftruncate(2) always changes the file timestamps, even if the
file size is not changed. However, in case of a successfull
truncate(2), the timestamps are updated only if the file size changes.
This translates to the VFS calling the ZFS Posix Layer "setattr"
function (zpl_setattr) with ATTR_MTIME and ATTR_CTIME unconditionally
set on the iattr mask only when doing a ftruncate(2), while the
truncate(2) is left to the filesystem implementation to be dealt with.

This behaviour is consistent with POSIX:2004/SUSv3 specifications
where there's no explicit requirement for file size changes to update
the timestamps only for ftruncate(2):

http://pubs.opengroup.org/onlinepubs/009695399/functions/truncate.html
http://pubs.opengroup.org/onlinepubs/009695399/functions/ftruncate.html

This has been later updated in POSIX:2008/SUSv4 where, for both
truncate(2)/ftruncate(2), there's no mention of this size change
requirement:

http://austingroupbugs.net/view.php?id=489
http://pubs.opengroup.org/onlinepubs/9699919799/functions/truncate.html
http://pubs.opengroup.org/onlinepubs/9699919799/functions/ftruncate.html

Unfortunately the Linux VFS is still calling into the ZPL without
ATTR_MTIME/ATTR_CTIME set in the truncate(2) case: we fix this by
explicitly updating the timestamps when detecting the ATTR_SIZE bit,
which is always set in do_truncate(), on the iattr mask.

71a24c3c52 Handle compressed buffers in __dbuf_hold_impl()
In __dbuf_hold_impl(), if a buffer is currently syncing and is still
referenced from db_data, a copy is made in case it is dirtied again in
the txg.  Previously, the buffer for the copy was simply allocated with
arc_alloc_buf() which doesn't handle compressed or encrypted buffers
(which are a special case of a compressed buffer).  The result was
typically an invalid memory access because the newly-allocated buffer
was of the uncompressed size.

This commit fixes the problem by handling the 2 compressed cases,
encrypted and unencrypted, respectively, with arc_alloc_raw_buf() and
arc_alloc_compressed_buf().

Although using the proper allocation functions fixes the invalid memory
access by allocating a buffer of the compressed size, another unrelated
issue made it impossible to properly detect compressed buffers in the
first place.  The header's compression flag was set to ZIO_COMPRESS_OFF
in arc_write() when it was possible that an attached buffer was actually
compressed.  This commit adds logic to only set ZIO_COMPRESS_OFF in
the non-ZIO_RAW case which wil handle both cases of compressed buffers
(encrypted or unencrypted).

Disable automatic dependencies in DKMS package
By default additional dependencies are generated automatically for
packages.  This is normally a good thing because it helps ensure
things just work.  It doesn't make sense for the DKMS package which
requires minimal dependencies that can be easily listed.

2df9ad1c07 Fix column alignment with long zpool names
`zpool status` normally aligns NAME/STATE/etc columns:

    NAME                       STATE     READ WRITE CKSUM
    dummy                      ONLINE       0     0     0
      mirror-0                 ONLINE       0     0     0
        /tmp/dummy-long-1.bin  ONLINE       0     0     0
        /tmp/dummy-long-2.bin  ONLINE       0     0     0
      mirror-1                 ONLINE       0     0     0
        /tmp/dummy-long-3.bin  ONLINE       0     0     0
        /tmp/dummy-long-4.bin  ONLINE       0     0     0

However, if the zpool name is longer than the zvol names, alignment
issues arise:

    NAME                  STATE     READ WRITE CKSUM
    dummy-very-very-long-zpool-name  ONLINE       0     0     0
      mirror-0            ONLINE       0     0     0
        /tmp/dummy-1.bin  ONLINE       0     0     0
        /tmp/dummy-2.bin  ONLINE       0     0     0
      mirror-1            ONLINE       0     0     0
        /tmp/dummy-3.bin  ONLINE       0     0     0
        /tmp/dummy-4.bin  ONLINE       0     0     0

`zpool iostat` and `zpool import` are also affected:

4fc411f7a3 initramfs: Set elevator=noop on the rpool's disks
ZFS already sets elevator=noop for wholedisk vdevs (for all pools), but
typical root-on-ZFS installations use partitions.  This sets
elevator=noop on the disks in the root pool.

Ubuntu 16.04 and 16.10 had this.  It was lost in 17.04 due to Debian
switching to this upstream initramfs script.

Porting Notes:
- The OpenZFS patch added nicenum_scale() and nicenum() to a
  library not used by ZFS.  Rather than pull in a new dependency
  the version of nicenum in lib/libzpool/util.c was simply
  replaced with the new one.
