Historically a dynamic misc minor number was registered for the
/dev/zfs device in order to prevent minor number collisions. This
was fine but it prevented us from being able to use the kernel
module auto-loaded which requires a known reserved value.
Resolve this issue by adding a configure test to find an available
misc minor number which can then be used in MODULE_ALIAS_MISCDEV at
build time. By adding this alias the zfs kmod is added to the list
of known static-nodes and the systemd-tmpfiles-setup-dev service
will create a /dev/zfs character device at boot time.
This in turn allows us to update the 90-zfs.rules file to make it
aware this is a static node. The upshot of this is that whenever
a process (zpool, zfs, zed) opens the /dev/zfs the kmods will be
automatic loaded. This even works for unprivileged users so there
is no longer a need to manually load the modules at boot time.
As an additional bonus the zed now no longer needs to start after
the zfs-import.service since it will trigger the module load.
In the unlikely event the minor number we selected conflicts with
another out of tree unregistered minor number the code falls back
to dynamically allocating it. In this case the modules again
must be manually loaded.
Note that due to the change in the method of registering the minor
number the zimport.sh test case may incorrectly fail when the
static node for the installed packages is created instead of the
dynamic one. This issue will only transiently impact zimport.sh
for this single commit when we transition and are mixing and
matching methods.

we do it very often.

Bandwidth and iops are average per second while *_wait are averages
per request for latency or, for queue depths, an instantaneous
measurement at the end of an interval (according to man zpool).
When calculating the first two it makes sense to do
x/interval_duration (x being the increase in total bytes or number of
requests over the duration of the interval, interval_duration in
seconds) to 'scale' from amount/interval_duration to amount/second.
But applying the same math for the latter (*_wait latencies/queue) is
wrong as there is no interval_duration component in the values (these
are time/requests to get to average_time/request or already an
absulute number).
This bug leads to the only correct continuous *_wait figures for both
latencies and queue depths from 'zpool iostat -l/q' being with
duration=1 as then the wrong math cancels itself (x/1 is a nop).
This removes temporal scaling from latency and queue depth figures.

needed to fit in a 32-bit unsigned long.
Unlike most other filesystems the total possible file counts
are more likely to overflow because they are calculated based
on the available free space in the pool. In order to prevent
this the reported value must be capped at 2^32-1. This is

Since zdb opens the pools read-only, it cannot damage the pool in the
event the pool is already imported either on the same host or on

If the pool vdev structure is changing while zdb is importing the
pool, it may cause zdb to crash. However this is unlikely, and in any
case it's a user space process and can simply be run again.
For this reason, zdb should disable the multihost activity test on
import that is normally run.
This commit fixes a few zdb code paths where that had been overlooked.
It also adds tests to ensure that several common use cases handle this

When doing a read from disk, ZFS creates 3 ZIO's: a zio_null(), the
logical zio_read(), and then a physical zio. Currently, each of these
results in a separate taskq_dispatch(zio_execute).
On high-read-iops workloads, this causes a significant performance
impact. By processing all 3 ZIO's in a single taskq entry, we reduce the
overhead on taskq locking and context switching. We accomplish this by
allowing zio_done() to return a "next zio to execute" to zio_execute().
This results in a ~12% performance increase for random reads, from
96,000 iops to 108,000 iops (with recordsize=8k, on SSD's).

This is a port of 047116ac - Raw sends must be able to decrease nlevels,
to the zfs-0.7-stable branch. It includes the various fixes to the
problem of receiving incremental streams which include reallocated dnodes
in which the number of dnode slots has changed but excludes the parts
which are related to raw streams.
From 047116ac:
Currently, when a raw zfs send file includes a
DRR_OBJECT record that would decrease the number of
levels of an existing object, the object is reallocated
with dmu_object_reclaim() which creates the new dnode
using the old object's nlevels. For non-raw sends this
doesn't really matter, but raw sends require that
nlevels on the receive side match that of the send
side so that the checksum-of-MAC tree can be properly
maintained. This patch corrects the issue by freeing
the object completely before allocating it again in
this case.
This patch also corrects several issues with
dnode_hold_impl() and related functions that prevented
dnodes (particularly multi-slot dnodes) from being
reallocated properly due to the fact that existing
dnodes were not being fully cleaned up when they
were freed.
This patch adds a test to make sure that zfs recv
functions properly with incremental streams containing
dnodes of different sizes.
This also includes a one-liner fix from loli10K to fix a test failure:
