Nick Black 4abd7d80b2 Remove parameter names from libzfs.h signatures
Most of libzfs.h doesn't provide names for the parameters
in its signatures. These few functions included them. That
wouldn't be a problem, per se, but the 'lines' parameter
conflicts with the 'lines' #define from terminfo's term.h,
present for at least a decade. This makes it difficult to
compile code making use of both ZFS and terminfo.

Ryan Moeller f8d55b95a5 ZTS: Eliminate functions named 'random'
The name overlaps with a command needed by FreeBSD.
There is also no sense having two 'random' functions that do nearly
the same thing, so consolidate to just the more general one and name
it 'random_int_between'.

lorenz 028e3b3b1a Avoid here-documents in systemd mount generator
On some systems - openSUSE, for example - there is not yet a writeable
temporary file system available, so bash bails out with an error,

  'cannot create temp file for here-document: Read-only file system',

on the here documents in zfs-mount-generator. The simple fix is to
change these into a multi-line echo statement.

DeHackEd 67709516db zfs-module-parameters(5): add all missing items
I ran a report against the output of `modinfo zfs.ko`. This commit adds
everything missing and corrects a few renamed module parameters.
Specifically:

* zfs_checksums_per second renamed in ad796b8a3
* vdev_ms_count_limit renamed in c853f382d

Also fixes some variable type inconsistencies (unsigned int => uint)

loli10K c24fa4b19a Fix "zpool add -n" for dedup, special and log devices
For dedup, special and log devices "zpool add -n" does not print
correctly their vdev type:

~# zpool add -n pool dedup /tmp/dedup special /tmp/special log /tmp/log
would update 'pool' to the following configuration:
	pool
	  /tmp/normal
	  /tmp/dedup
	  /tmp/special
	  /tmp/log

This could lead storage administrators to modify their ZFS pools to
unexpected and unintended vdev configurations.

Fix QAT allocation failure return value
When qat_compress() fails to allocate the required contiguous memory
it mistakenly returns success.  This prevents the fallback software
compression from taking over and (un)compressing the block.

Resolve the issue by correctly setting the local 'status' variable
on all exit paths.  Furthermore, initialize it to CPA_STATUS_FAIL
to ensure qat_compress() always fails safe to guard against any
similar bugs in the future.

ZTS: Cleanup partition tables
The cleanup_devices function should remove any partitions created
on the device and force the partition table to be reread.  This
is needed to ensure that blkid has an up to date version of what
devices and partitions are used by zfs.

The cleanup_devices call was removed from inuse_008_pos.ksh since
it operated on partitions instead of devices and was not needed.

Lastly ddidecode may be called by parted and was therefore added
to the constrained path.

Garrett Fields e8b199faec Force systems with kernel option "quiet" to display prompt for password
On systems that utilize TTY for password entry, if the kernel 
option "quiet" is set, the system would appear to freeze on a 
blank screen, when in fact it is waiting for password entry 
from the user.

Since TTY is the fallback method, this has no effect on systemd 
or plymouth password prompting.

By temporarily setting "printk" to "7", running the command, 
then resuming with the original "printk" state, the user can 
see the password prompt.

Richard Laager ad97643773 initramfs: setup keymapping and video for prompts
From Steve Langasek <steve.langasek@canonical.com>:
> The poorly-named 'FRAMEBUFFER' option in initramfs-tools controls
> whether the console_setup and plymouth scripts are included and used
> in the initramfs. These are required for any initramfs which will be
> prompting for user input: console_setup because without it the user's
> configured keymap will not be set up, and plymouth because you are
> not guaranteed to have working video output in the initramfs without
> it (e.g. some nvidia+UEFI configurations with the default GRUB
> behavior).

> The zfs initramfs script may need to prompt the user for passphrases
> for encrypted zfs datasets, and we don't know definitively whether
> this is the case or not at the time the initramfs is constructed (and
> it's difficult to dynamically populate initramfs config variables
> anyway), therefore the zfs-initramfs package should just set
> FRAMEBUFFER=yes in a conf snippet the same way that the
> cryptsetup-initramfs package does
> (/usr/share/initramfs-tools/conf-hooks.d/cryptsetup).

Tom Caputi c317c8c811 Allow empty ds_props_obj to be destroyed
Currently, 'zfs list' and 'zfs get' commands can be slow when
working with snapshots that have a ds_props_obj. This is
because the code that discovers all of the properties for these
snapshots needs to read this object for each snapshot, which
almost always ends up causing an extra random synchronous read
for each snapshot. This performance penalty exists even if the
properties on that snapshot have been unset because the object
is normally only freed when the snapshot is freed, even though
it is only created when it is needed.

This patch allows the user to regain 'zfs list' performance on
these snapshots by destroying the ds_props_obj when it no longer
has any entries left. In practice on a production machine, this
optimization seems to make 'zfs list' about 55% faster.
