- Limit ARC for zdb at 256MB.  zdb do not typically revisit data
   in the ARC.
 - Increase default max_inflight from 200 to 1000 (can be overriden
   by -I) so we can queue more I/Os when doing scrubbing.
 - Print status while loading meataslabs for leak detection.

Illumos issues:

    5169 zdb should limit its ARC size
    5170 zdb -c should create more scrub i/os by default
    5171 zdb should print status while loading metaslabs for leak detection

41da933c87 Hook up support for userland CTF support in DTrace. This required some
modifications to libproc to support fetching the CTF info for a given file.

With this change, dtrace(1) is able to resolve type info for function and
USDT probe arguments, and function return values. In particular, the args[n]
syntax should now work for referencing arguments of userland probes,
provided that the requisite CTF info is available.

The uctf tests pass if the test programs are compiled with CTF info. The
current infrastructure around the DTrace test suite doesn't support this
yet.

486de25d46 Have dtrace(1) handle SIGPIPE by cleaning up and exiting. Additionally,
install signal handlers when running in list mode (-l), and acknowledge
interrupts by cleaning up and exiting. This ensures that a command like

$ dtrace -l -P 'pid$target' -p <target PID> | less

won't cause the ptrace(2)d target process to be killed if less(1) exits
before all dtrace output is consumed.

c63a110d6d zfs_setprop_error(): Handle errno value E2BIG.
This errno value is emitted by dsl_props_set_check() in
sys/cddl/contrib/opensolaris/uts/common/fs/zfs/dsl_prop.c, and
is used to mean that the property value is too long.  For the record,
the maximum length is ZAP_MAXVALUELEN, which is 8*1024 bytes.

Instead of claiming an unknown error (and abort()ing), provide
something more specific to the scenario involved.  As far as I
can tell, E2BIG is not emitted for any other scenario.

Instead of asserting all zio's be properly aligned, only assert

This fixes a problem that zdb would trip assert on pools with

7079d5877c MFV r268714:
Improve extreme rewind import.

When doing an "extreme rewind" import ("zpool import -XF"), we attempt
to verify all data in the pool, essentially scrubbing the entire pool.
The problem is that spa_load_verify_cb() issues an unbounded number of
concurrent scrub i/os.  This can lead to all of memory being used for
these zio's, wedging the system. Like normal scrub, we need to put a
cap on the number of outstanding i/os, and have the traverse thread
block when we reach this cap.

For this purpose the cap can be very large (10,000) to optimize the
elevator algorithm.  Three kernel tunables have been added:

	vfs.zfs.spa_load_verify_maxinflight
	vfs.zfs.spa_load_verify_metadata
	vfs.zfs.spa_load_verify_data

The latter two tunables controls whether metadata and/or user data
when doing extreme rewind.

Make 'zpool import -T' imply scrub.

Make zpool import -T <txg> accept hexadecimal values for the txg when
prefixed with 0x.

Skip txg's for which there is no uberblock when doing extreme rewind.

Skip reading all user data twice by skipping prefetches when doing
extreme rewinds as we do not access via the ARC.

Illumos issues:
  4970 need controls on i/o issued by zpool import -XF
  4971 zpool import -T should accept hex values
  4972 zpool import -T implies extreme rewind, and thus a scrub
  4973 spa_load_retry retries the same txg
  4974 spa_load_verify() reads all data twice

1b174fa1eb MFV r268455:
Use reserved space for ZFS administrative commands.

We reserve 1/2^spa_slop_shift = 1/32 or 3.125% of pool space (or 32MB at
least) for system use.  Most ZPL operations, e.g. write(2), creat(2), will
fail with ENOSPC if we fall below this.

Certain operations, e.g. file removal and most administrative actions,
still permitted until half of the slop space is used.  This would allow
users to use these operations to free up space in the pool when pool is
close to full but half of slop space is still free.

A very restricted set of operations that frees up space or change quota
are always permitted, regardless of the amount of free space.
