processing, this actually means there's a double slash recorded in the
symbolic link's path name. We used to start over from / then, which
caused link targets like ../../bsdi.1.0/include//pathnames.h to be
interpreted as /pathnahes.h. This is both contradictionary to our
conventional slash interpretation, as well as potentially dangerous.
The right thing to do is (obviously) to just ignore that element.
bde once pointed out that mistake when he noticed it on the
4.4BSD-Lite2 CD-ROM, and asked me for help.

this. This makes e.g. "mount -r /usr" or "mount -ar" actually
mount file systems read-only.
to be 'long' instead of 'int' so that sysctl(8) correctly displays
the 8 returned bytes as a single 'long' instead of two 'int' values.

- Speed up synchronization process by using configurable number of I/O
requests in parallel.
+ Add kern.geom.raid3.sync_requests tunable which defines how many parallel
I/O requests should be used.
+ Retire kern.geom.raid3.reqs_per_sync and kern.geom.raid3.syncs_per_sec
sysctls.
- Fix race between regular and synchronization requests.
- Reimplement raid3's data synchronization - do not use the topology lock
for this purpose, as it may case deadlocks.
- Stop synchronization from pre-sync hook.
- Fix some other minor issues.

o call firmware_put() early to release the firmware module
o on firmware panics or watchdog timeouts, schedule a task to reinitialize
the interface (we may sleep in iwi_init())
o discard oversized rx frames
This does not do what I wanted as all dirty buffers must be flushed
by the call to ffs_sync and any remaining dependency work would mean
that this failed.

Fix detection of active unlinked files by checking VI_OWEINACT and
VI_DOINGINACT in addition to v_usecount.
Defer inactive handling for unlinked files if the file system is mostly
suspended (secondary writes being blocked).
Perform deferred inactive handling after the file system is resumed.
flag isn't enough - the filter needs to be set up too, or no multicast frames
are accepted.

Use 'BOOT_SENSITIVE_INFO=YES' variable to turn them on.
- Use 'uint*_t' instead of 'u_int*_t', correct compilation warnings, and
update copyright while I am here.
In at least one benchmark this showed around a 20% performance increase.
If other workloads do benefit from having hyperthreads service interrupts,
we can always make this a loader tunable.
