As a result, the kernel needs to process shorter pathnames if fts is not
changing directories (if fts follows symlinks (-L option to utilities), fts
cannot open "." or FTS_NOCHDIR was specified).
Side effect: If pathnames exceed PATH_MAX, [ENAMETOOLONG] is not hit at the
stat stage but later (opendir or application fts_accpath) or not at all.
vm_pageout_scan(). There were missing increments in two less common cases.
Don't conflate the count of stuck pages and the pageout deficit provided by
vm_page_alloc{,_contig}(). (A proposed fix to the OOM code depends on this.)
Handle held pages consistently in the inactive queue scan. In the more
common case, we did not move the page to the tail of the queue. Whereas, in
the less common case, we did. There's no particular reason to move the page
in the less common case, so remove it.
Perform the calculation of the page shortage for the active queue scan a
little earlier, before the active queue lock is acquired. The correctness
of this calculation doesn't depend on the active queue lock being held.
Eliminate a redundant variable, "pcount". Use the more descriptive
variable, "maxscan", in its place.
Apply a few nearby style fixes, e.g., eliminate stray whitespace and excess
parentheses.

After r252890 we are naively attempting to pass through the
inode flags. This is technically incorrect as the ext2
inode flags don't match the UFS/system values used in
FreeBSD and a clean conversion is needed.
Some filtering was left in place so the change didn't cause
significant changes in FreeBSD but some of the garbage passed
is likely to be the cause for warning messages in linux.
Fix the issue by resetting the flags before conversion as was
done previously. This also means we will not pass the EXT4_*
inode flags into FreeBSD's inode.

inject interrupts into the guest without causing a VM-exit.
This feature can be disabled by setting the tunable "hw.vmm.vmx.use_apic_pir"
to "0".
The following sysctls provide information about this feature:
- hw.vmm.vmx.posted_interrupts (0 if disabled, 1 if enabled)
- hw.vmm.vmx.posted_interrupt_vector (vector number used for vcpu notification)
Tested on a Intel Xeon E5-2620v2 courtesy of Allan Jude at ScaleEngine.
This control is needed to enable "Posted Interrupts" and is present in all
the Intel VT-x implementations supported by bhyve so enable it as the default.
With this VM-exit control enabled the processor will acknowledge the APIC and
store the vector number in the "VM-Exit Interruption Information" field. We
now call the interrupt handler "by hand" through the IDT entry associated
with the vector.
Because we respect the FreeBSD src tree layout under /usr/tests, and because
the layout of the tests in the atf distfile does not match the former, the
tests for atf-c++ were not able to find the process_helper binary.
Fix this by explicitly hardcoding the right path in the FreeBSD test suite.

Put test programs for internal modules into a 'detail' subdirectory of the

does. This is necessary because the tests assume such layout to find the

Sending both RTM_ADD/RTM_DELETE messages to rtsock is completely wrong
(and requires some hacks to keep prefix in route table on RTM_DELETE).
I've tested this change with quagga (no change) and bird (*).
bird alias handling is already broken in *BSD sysdep code, so nothing
changes here, too.
I'm going to MFC this change if there will be no complains about behavior
change.

One of the tests for test(1) fails and some of the tests for sh(1) are
silently bypassed when running as root.
To fix these tests and ensure they all run, mark the test programs for

When generating a Kyuafile in the KYUAFILE=auto case, use a filename
that is unlikely to clash with the filename used by explicitly-provided
Kyuafiles.
This allows a Makefile to set KYUAFILE=yes and provide a Kyuafile in
the same directory when such Makefile was previously relying on
KYUAFILE=auto.
Fixes issues with new Kyuafiles not being picked up in NO_CLEAN builds
(although manual intervention is required once, unfortunately, as
described in UPDATING).
