Althought cryptotest itself has a -z mode to test all algorithms at a variety
of sizes, this script allows us to be more selective. Threads and buffer sizes
move in powers of two from 1, for threads, and 256 for buffer sizes.
e.g. cryptorun.sh aes 4 512
Test aes with 1, 2 and 4 processes, and at sizes of 256 and 512 bytes.

important detail that sc_cngetc() now opens and closes the keyboard
on every call again. This was moved from sc_cngetc() to scn_cngrab/
ungrab() in r228644, but the change wasn't quite complete. After
fixes for nesting in kbdd_poll() in ukbd and kbdmux, these opens
and closes should have no significant effect if done while grabbed.
They fix unusual cases when cngetc() is called while not grabbed.
This commit is the main fix for screen locking in sc_cnputc():
detect deadlock or likely-deadlock and handle it by buffering the
output atomically and printing it later if the deadlock condition
clears (and sc_cnputc() is called).
The most common deadlock is when the screen lock is held by ourself.
Then it would be safe to acquire the lock recursively if the console
driver is calling printf() in a safe context, but we don't know when
that is. It is not safe to ignore the lock even in kdb or panic mode.
But ignore it in panic mode. The only other known case of deadlock
is when another thread holds the lock but is running on a stopped CPU.
Detect that case approximately by using trylock and retrying for 1000
usec. On a 4 GHz CPU, 100 usec is almost long enough -- screen switches
take slightly longer than that. Not retrying at all is good enough
except for stress tests, and planned future versions will extend the
timeout so that the stress tests work better.
To see the behaviour when deadlock is detected, single step through
sctty_outwakeup() (or sc_puts() to start with deadlock). Another
(serial) console is needed to the buffered-only output, but the
keyboard works in this context to continue or step out of the
deadlocked region. The buffer is not large enough to hold all the
output for this.
7136 ESC_VDEV_REMOVE_AUX ought to always include vdev information

6922 added ESC_ZFS_VDEV_REMOVE_AUX and ESC_ZFS_VDEV_REMOVE_DEV sysevents
whenever an aux device gets removed from a pool. However, those sysevents will
be created without the vdev_guid and vdev_path fields. It would be better to
always populate those fields.

The addition of spa_event_notify in vdev removal code (see #6922) causes event
s
to be generated even if the spare failed to be removed with EBUSY.

The current default indirect block size is 16KB. We can improve
performance by increasing it to 128KB. This is especially helpful for
any workload that needs to read most of the metadata, e.g.
scrub/resilver, file deletion, filesystem deletion, and zfs send.
We also need to fix a few space estimation errors to make the tests
pass.
