swp_pager_force_pagein(). By dirtying the page, swp_pager_force_pagein()
forces vm_page_dontneed() to insert the page at the head of the inactive
queue, just like vm_page_deactivate() does. Moreover, because the page
was invalid, it can't have been mapped, and thus the other effect of
vm_page_dontneed(), clearing the page's reference bits has no effect. In
summary, there is no reason to call vm_page_dontneed() since its effect
will be identical to calling the simpler vm_page_deactivate().
Note: clock accepts CLOCK_VIRTUAL and CLOCK_PROF too, but this seems broken
as it simply waits for the difference of the current and given value of the
clock as if it were CLOCK_MONOTONIC. So document only CLOCK_REALTIME and
CLOCK_MONOTONIC as allowed.

hid_get_data() now expects that the hid data passed in always contains
the report ID byte. Thus we should not skip the the report ID byte in
hid_interrupt(). Also, if HUP_KEYBOARD usage is an array, do not try
to modify the 'data' pointer, instead, increase the hid_item_t field
'pos' by 'report_size' before calling hid_get_data() during each
iteration.

table. The default size of the configuration table was 22 bytes. To
use extended feature of 82550/82551 the configuration table size
was expanded to 32 bytes. The added configuration for 82550/82551
specifies VLAN hardware tagging and IPSec configuration as well as
TCO.
To make configuration easier fxp(4) used a configuration template
and the template was copied to configuration table. After that,
some parameters of the configuration table was changed depending on
controller type and operation mode. However the size of template
was 22 bytes so some configuration parameters were not properly
initialized on 82550/82551.
Fix this by increasing the template size. For 82557, 82558 and
82559 the size of the configuration is still 22 bytes.

that host didn't join in promiscuous mode, driver have to set

The Open Source Software Developer Manual for i8255x was not clear
how to handle promiscuous mode.

This joint work of Dag-Erling Smørgrav and myself updates the
FFS quota system to support both traditional 32-bit and new 64-bit
quotas (for those of you who want to put 2+Tb quotas on your users).
By default quotas are not compiled into the kernel. To include them
in your kernel configuration you need to specify:
options QUOTA # Enable FFS quotas
If you are already running with the current 32-bit quotas, they
should continue to work just as they have in the past. If you
wish to convert to using 64-bit quotas, use `quotacheck -c 64';
if you wish to revert from 64-bit quotas back to 32-bit quotas,
use `quotacheck -c 32'.
There is a new library of functions to simplify the use of the
quota system, do `man quotafile' for details. If your application
is currently using the quotactl(2), it is highly recommended that
you convert your application to use the quotafile interface.
Note that existing binaries will continue to work.
Special thanks to John Kozubik of rsync.net for getting me
interested in pursuing 64-bit quota support and for funding
part of my development time on this project.
sigvec(2) references have been updated to sigaction(2), sigsetmask(2) and

Some legacy man pages still refer to them, that is OK.
