run through copy-on-write. Call fscow_run() with valid data where possible.
The LP_UFSCOW hack is no longer needed to protect ffs_copyonwrite() against
endless recursion.
- Add a flag B_MODIFY to bread(), breada() and breadn(). If set the caller
intends to modify the buffer returned.
- Always run copy-on-write on buffers returned from ffs_balloc().
- Add new function ffs_getblk() that gets a buffer, assigns a new blkno,
may clear the buffer and runs copy-on-write. Process possible errors
from getblk() or fscow_run(). Part of PR kern/38664.

- Convert hashinit() to use kmem_alloc(). The hash tables can be large
and it's better to not have them in kmem_map.
- Convert a couple of minor items along the way to kmem_alloc().
- Fix some memory leaks.
into the kernel. Based on a patch by jmcneill@, with many fixes and
improvements by me.
- Put MEMORY_DISK_DYNAMIC and MODULAR into the GENERIC kernels, so that
you can load miniroot.kmod from the boot blocks and boot into the
installer!
BUFQ_CANCEL(queue, element) removes the specified element previously queued
on the queue. It returns NULL if it was not found on the queue and the
element if it was successfully removed.
Run trough tech-kern and changed name from BUFQ_REVOKE() by suggestion of
Jason Thorpe.
Changes beyond OpenBSD's driver:
- Improved support for AMD K8
- Added support for AMD Barcelona, AMD Phenom and AMD Griffin
Tested on various single and multi-socket machines.
Review and OK xtreame
btuartd(8) should be named btattach(8) for consistency
with other parts of NetBSD
make btattach(8) a single-use tool for less complexity
device specicific initialisation (from btuart(4)) is carried
out prior to activating the line discipline (in btattach(8)),
which simplifies the API somewhat and means that the user
tool and the kernel do not need to be kept in sync.
btuart(4) driver is much reduced; naming is made consistent
and all tsleep() and delay() are removed to userland
* Asynchronous operation with result retrieval via select/poll
* Mutliple-request submit/retrieve ioctls
* Mutliple-session create-destroy ioctls
Revise/rewrite crypto.4 manual page. It should now be much easier to write
new applications to this API.
Measured performance for trivial requests: 84,000 very short modular math
operations/sec, 120,000 very short md5 hashes per sec (with a hardware
accellerator of moderate performance but very low latency, whose driver
will be contributed at a later date).
