While investigating https://github.com/zfsonlinux/zfs/issues/6425 I
noticed that ioctl ZIOs were not setting zio->io_delay correctly. They
would set the start time in zio_vdev_io_start(), but never set the end
time in zio_vdev_io_done(), since ioctls skip it and go straight to
zio_done(). This was causing spurious "delayed IO" events to appear,
which would eventually get rate-limited and displayed as
"Missed events" messages in zed.
To get around the problem, this patch only sets zio->io_delay for read
and write ZIOs, since that's all we care about anyway.

Redefine the SET_ERROR macro in terms of __dprintf() so the error
return codes get logged as both tracepoint events (if tracepoints are
enabled) and as ZFS debug log entries. This also allows us to use
the same definition of SET_ERROR() in kernel and user space.
Define a new debug flag ZFS_DEBUG_SET_ERROR=512 that may be bitwise
or'd into zfs_flags. Setting this flag enables both dprintf() and
SET_ERROR() messages in the debug log. That is, setting
ZFS_DEBUG_SET_ERROR and ZFS_DEBUG_DPRINTF|ZFS_DEBUG_SET_ERROR are
equivalent (this was done for sake of simplicity). Leaving
ZFS_DEBUG_SET_ERROR unset suppresses the SET_ERROR() messages which
helps avoid cluttering up the logs.
To enable SET_ERROR() logging, run:
echo 1 > /sys/module/zfs/parameters/zfs_dbgmsg_enable
echo 512 > /sys/module/zfs/parameters/zfs_flags
Remove the zfs_set_error_class tracepoints event class since
SET_ERROR() now uses __dprintf(). This sacrifices a bit of
granularity when selecting individual tracepoint events to enable but
it makes the code simpler.
Include file, function, and line number information in debug log
entries. The information is now added to the message buffer in
__dprintf() and as a result the zfs_dprintf_class tracepoints event
class was changed from a 4 parameter interface to a single parameter.

Turning the multihost property on requires that a hostid be set to allow
ZFS to determine when a foreign system is attemping to import a pool.
The error message instructing the user to set a hostid refers to
genhostid(1).
Genhostid(1) is not available on SUSE Linux. This commit adds a script
modeled after genhostid(1) for those users.
Zgenhostid checks for an /etc/hostid file; if it does not exist, it
creates one and stores a value. If the user has provided a hostid as an
argument, that value is used. Otherwise, a random hostid is generated
and stored.
This differs from the CENTOS 6/7 versions of genhostid, which overwrite
the /etc/hostid file even though their manpages state otherwise.
A man page for zgenhostid is added. The one for genhostid is in (1), but
I put zgenhostid in (8) because I believe it's more appropriate.
The mmp tests are modified to use zgenhostid to set the hostid instead
of using the spl_hostid module parameter. zgenhostid will not replace
an existing /etc/hostid file, so new mmp_clear_hostid calls are
required.

When an IO fails then zio_vdev_io_done() can call vdev_probe()
to determine the health of the vdev. This is safe as long as
the original zio was submitted with zio_wait() and holds the
SCL_STATE_ALL lock over the operation.
If zio_no_wait() was used then the done callback will submit
the probe IO outside the SCL_STATE_ALL lock and hit this
ASSERT in zio_create()
ASSERT(!vd || spa_config_held(spa, SCL_STATE_ALL, RW_READER));
Resolve the issue by only allowing vdev_probe() to be called
when there's a waiter indicating the caller is using zio_wait().
This assumes that caller is still holding SCL_STATE_ALL.
This issue isn't MMP specific but was surfaced when testing.

If no spl_hostid was set, and no /etc/hostid file existed, the user
and kernel would have different values for the hostid.
The kernel's would be 0. User space's would depend on the libc
implementation. On systems with glibc, it would be a generated value,
probably the first 4 bytes of an IP address (see man 3 gethostid and
comments above hostid_read in SPL for details).
This then causes the hostid stored in the labels and in the pool
config not to match the hostid userspace obtains from
get_system_hostid().
Since the kernel has no way to know the libc's generated hostid value,
it serves no purpose for ZFS to use the value.
This patch changes user space's get_system_hostid() to conform to the
kernel's method, first checking for the spl_hostid via sysfs, and then
reading from /etc/hostid directly.
It does not look up spl_hostid_path, because if that is set and the
file it pointed to exists, spl_hostid will reflect its contents.
It eliminates the call to libc's gethostid().

Closes#6300Closes#6323
The sync thread is concurrently modifying dn_phys->dn_nlevels
while dbuf_dirty() is trying to assert something about it, without
holding the necessary lock. We need to move this assertion further down
in the function, after we have acquired the dn_struct_rwlock.

Call dpkg-shlibdeps with arguments excluding the Debianized packages
lib{uutil1,nvpair1,zfs2,zpool2}linux from the auto-generated
dependencies of generated .debs. A shim dh_shlibdeps that calls the
real dh_shlibdeps with corresponding arguments is installed into a
temporary directory, which is in turn pre-pended to the PATH for the
alien call, working around alien's inability to directly alter the
dependencies of its output debs. Resolves#6106.

this by reintroducing a check (POOL_CHECK_READONLY) in zfs_ioc_clear
registration code.
