kernel memory leakage to userspace. For the typical use, when a
filesystem put on the md disk, the change only results in CPU and
memory bandwidth spent to zero the page, since filsystems make sure
that user never see unwritten content. But if md disk is used as raw
device by userspace, the garbage is exposed.

to further reduce latency for threads in this queue. This should help
as threads transition from realtime to timeshare. The latency is
bound to a max of sched_slice until we have more than sched_slice / 6
threads runnable. Then the min slice is allotted to all threads and
latency becomes (nthreads - 1) * min_slice.

solve power loss problems with dishonest write caches. However, it
should improve the situation and force a full fsck when it is unable
to resolve with the journal.
- Resolve a case where the journal could wrap in an unsafe way causing
us to prematurely lose journal entries in very specific scenarios.

on timing of the operations and not real lookup, bringing too many
false positives. Remove the whole mechanism. If it needs to be
implemented, next time it should really be done in the proper way.
- Fix VOP_GETATTR() in order to cope with userland bugs that would
change the type of file and not panic. Instead it gets the entry as
if it is not existing.

sorting order for time and name with the -t option. IEEE Std 1003.2
(POSIX.2) mandates that the -t option sort in descending order, and
that if two files have the same timestamp, they should be sorted in
ascending order of their names. The -r flag reverses both of these
sort orders, so they're never the same. This creates significant
problems for sequentially named files stored on FAT file systems,
where it can be impossible to list them in the order in which they
were created.
Add , (comma) option to print file sizes grouped and separated by
thousands using the non-monetary separator returned by localeconv(3),
typically a comma or period.

There is one known issue: Some probes will display an error message along the
lines of: "Invalid address (0)"
I tested this with both a simple dtrace probe and dtruss on a few different
binaries on 32-bit. I only compiled 64-bit, did not run it, but I don't expect
problems without the modules loaded. Volunteers are welcome.

default compiler. This has two parts:
- Make sys/boot/pc98/boot2 always build with gcc for now, until we can
figure out a way to shrink it enough when building with clang.
- Since sys/boot/p98/cdboot uses .code16 directives, which are not yet
supported by clang's integrated assembler, use -no-integrated-as,
similar to sys/boot/i386/cdboot.

rewrite the way states from pfsync are merged into the local state tree
and the conditions on which pfsync will notify its peers on a stale update.
each side (ie, the sending and receiving side) of the state update is
compared separately. any side that is further along than the local state
tree is merged. if any side is further along in the local state table, an
update is sent out telling the peers about it.
case keys had already been freed. If encountering such state, then
just release last reference.
Not sure this can happen as a runtime race, but can be reproduced by
the following scenario:
- enable pfsync
- disable pfsync
- wait some time
- enable pfsync
ps-poll is totally broken in its current form.
This should unbreak things enough to let people use PS-POLL devices,
but leave it in place for me to finish PS-POLL handling.
function use that for JBOD and Thunderbolt disk write command. Now
we only have one implementation in mfi.
- Fix dumping on Thunderbolt cards. Polled IO commands do not seem to
be normally acknowledged by changing cmd_status to MFI_STAT_OK.
In order to get acknowledgement of the IO is complete, the Thunderbolt
command queue needs to be run through. I added a flag MFI_CMD_SCSI
to indicate this command is being polled and to complete the
Thunderbolt wrapper and indicate the result. This flag needs to be
set in the JBOD case in case if that us using Thunderbolt card.
When in the polling loop check for completed commands.
- Remove mfi_tbolt_is_ldio and just do the check when needed.
- Fix an issue when attaching of disk device happens when a device is
already scheduled to be attached but hasn't attached.
- add a tunable to allow raw disk attachment to CAM via:
hw.mfi.allow_cam_disk_passthrough=1
- fixup aborting of commands (AEN and LD state change). Use a generic
abort function and only wait the command being aborted not both.
Thunderbolt cards don't seem to abort commands so the abort times
out.
