MFV r275914:

As of r270383, the dbuf_compare comparator compares the dbuf
attributes in the following order:

        db_level (indirect level)
        db_blkid (block number)
        db_state (current state)
        the address of the element

Because db_state is being considered before the element's state,
changing of db_state would affect balancedness of the AVL tree,
even when the address of element compares differently.  For
instance, in dbuf_create, db_state may be altered after the
node is inserted into the AVL tree and may break AVL tree
balancedness.

Instead of using db_state as a comparision critera (introduced
in r270383), consider it only when we are doing a lookup, that
is one of the two dbuf pointers contains DB_SEARCH.

Fix building/installing tests when TESTSBASE != /usr/tests

The work in r258233 hardcoded the assumption that tests was the last component
of the tests tree by pushing tests as an explicit prefix for the paths in
BSD.tests.dist and /usr was the prefix for all tests, per BSD.usr.dist and all
of the mtree calls used in Makefile.inc1. This assumption breaks if/when one
provides a custom TESTSBASE "prefix", e.g. TESTSBASE=/mytests .

One thing that r258233 did properly though was remove "/usr/tests" creation
from BSD.usr.dist -- that should have not been there in the first place. That
was an "oops" on my part for the work that was originally committed in r241823

Don't deselect the card too soon. To set the block size or switch the
function parameters, the card has to be in transfer state. If it is in
the idle state, the commands are ignored. This caused us not to set
the proper parameters that we later assume to be present, leading to
downstream failures of the card / interface as our state machine
mismatches the card's.

FreeBSD — head/sys/cddl/contrib/opensolaris/uts/common/fs/zfs zfs_vnops.c, head/sys/fs/ext2fs ext2_lookup.c

The VOP_LOOKUP() implementations for CREATE op do not put the name
into namecache, to avoid cache trashing when doing large operations.
E.g., tar archive extraction is not usually followed by access to many
of the files created.

Right now, each VOP_LOOKUP() implementation explicitely knowns about
this quirk and tests for both MAKEENTRY flag presence and op != CREATE
to make the call to cache_enter().  Centralize the handling of the
quirk into VFS, by deciding to cache only by MAKEENTRY flag in VOP.
VFS now sets NOCACHE flag for CREATE namei() calls.

Note that the change in semantic is backward-compatible and could be
merged to the stable branch, and is compatible with non-changed
third-party filesystems which correctly handle MAKEENTRY.

MFC r275482: Document r275481 changes.

FreeBSD — stable/10/sys/cam/ctl ctl.c ctl_private.h, stable/10/usr.sbin/ctladm ctladm.8

MFC r275568:
Count consecutive read requests as blocking in CTL for files and ZVOLs.

Technically read requests can be executed in any order or simultaneously
since they are not changing any data.  But ZFS prefetcher goes crasy when
it receives consecutive requests from different threads.  Since prefetcher
works on level of separate blocks, instead of two consecutive 128K requests
it may receive 32 8K requests in mixed order.

This patch is more workaround then a real fix, and it does not fix all of
prefetcher problems, but it improves sequential read speed by 3-4x times
in some configurations.  On the other side it may hurt performance if
some backing store has no prefetch, that is why it is disabled by default
for raw devices.

Add to CTL support for threshold notifications for file-backed LUNs.

Previously it was supported only for ZVOL-backed LUNs, but now should work
for file-backed LUNs too.  Used value in this case is a space occupied by
the backing file, while available value is an available space on file
system.  Pool thresholds are still not implemented in this case.

Do not pre-allocate UNIT ATTENTIONs storage for every possible initiator.

Abusing ability of major UAs cover minor ones we may not account UAs for

Do not pre-allocate reservation keys memory for every possible initiator.

MFC r275058: Coalesce last data move and command status for read commands.

Make CTL core and block backend set success status before initiating last
data move for read commands.  Make CAM target and iSCSI frontends detect
such condition and send command status together with data.  New I/O flag
allows to skip duplicate status sending on later fe_done() call.

For Fibre Channel this change saves one of three interrupts per read command,
increasing performance from 126K to 160K IOPS.  For iSCSI this change saves
one of three PDUs per read command, increasing performance from 1M to 1.2M
IOPS.

MFC r274962:  Replace home-grown CTL IO allocator with UMA.

Old allocator created significant lock congestion protecting its lists
of preallocated I/Os, while UMA provides much better SMP scalability.
The downside of UMA is lack of reliable preallocation, that could guarantee
successful allocation in non-sleepable environments.  But careful code
review shown, that only CAM target frontend really has that requirement.
Fix that making that frontend preallocate and statically bind CTL I/O for
every ATIO/INOT it preallocates any way.  That allows to avoid allocations
in hot I/O path.  Other frontends either may sleep in allocation context
or can properly handle allocation errors.

On 40-core server with 6 ZVOL-backed LUNs and 7 iSCSI client connections
this change increases peak performance from ~700K to >1M IOPS!  Yay! :)

FreeBSD — head/sys/net80211 ieee80211_scan_sta.c

Fix the scan handling for 11b->11g upgrades in a world where, well,
it's not just 11b/11g.

The following was happening, and it's quite .. annoyingly grr-y.

* create vap, setup wpa_supplicant with no bgscanning, etc - there's
  no call to ieee80211_media_change, so vap->iv_des_mode is
  IEEE80211_MODE_AUTO;
* do ifconfig wlan0 scan - same thing, media_change doesn't get called,
  iv_des_mode stays as auto.
* But then, run wpa_cli and do 'scan' - it'll do a media change.
* if you're on 11ng, vap->iv_des_mode gets changed to IEEE80211_MODE_11NG
* Then makescanlist() is called.  There's a block of code that gets
  called if iv_des_mode != IEEE80211_MODE_AUTO, and it does this:

                if (vap->iv_des_mode != IEEE80211_MODE_11G ||
                            mode != IEEE80211_MODE_11B)
                        continue;
                mode = IEEE80211_MODE_11G;        /* upgrade */

* .. now, iv_des_mode is not IEEE80211_MODE_11G, so it always runs
  'continue'
* .. and thus the scan list stays empty and no further channel
  scans occur. Ever.(1)

FreeBSD — head/usr.sbin/bsdinstall/distextract distextract.c Makefile

In bsdinstall's distextract, replace mixed_gauge() of dialog(3) with
new dpv(3) wrapper to dialog(3) dialog_gauge(). The dpv(3) library provides
a more flexible and refined interface similar to dialog_mixedgauge() however
is implemented atop the more generalized dialog_gauge() for portability.
Noticeable improvements in bsdinstall's distextract will be a status line
showing data rate information (with support for localeconv(3) to format
numbers according to $LANG or $LC_ALL conversion information), i18n support,
improved auto-sizing of gauge widget, a ``wheel barrow'' to keep the user
informed that things are moving (even if status/progress has not changed),
improved color support (mini-progress bars use the same color, if enabled,
as the main gauge bar), and several other improvements (some not visible).
dpv stands for "dialog progress view" (dpv was introduced in SVN r274116).
