sending a termios(4) structure like it was supposed to: ptcread() used
to copy pti->pt_send and zero it before testing it for TIOCPKT_IOCTL.
Test for TIOCPKT_IOCTL in the pti->pt_send copy in local variable c
instead of in pti->pt_send itself.
- create md devices on first open and destroy on last close.
- add enough disk label support to make DIOCGDINFO and DIOCGPART work.
- add disk_busy()/disk_unbusy() instrumentation.

protect wl_dealloc* members. Take the mutex here and change the lock
requirements of these fields to "writer lock or mutex".
This error lead to file system corruption and "freeing free block" panics.
XXX: using timo == 0 to mean "sleep as long as you like, and forever
if you're really tired" is not the smartest interface considering
the the hz/n idiom used to specify timo. This leads to unwanted
behaviour when hz gets below some impossible-to-know limit. With
a usec2ticks() routine it at least be a little more tolerable.
1. Fix inverted node order, so that negative value from comparison operator
would represent lower (left) node, and positive - higher (right) node.
2. Add an argument (i.e. "context"), passed to comparison operators.
3. Change rb_tree_insert_node() to return a node - either inserted one or
already existing one.
4. Amend the interface to manipulate the actual object, instead of the
rb_node (in a similar way as Patricia-tree interface does).
5. Update all RB-tree users accordingly.
XXX: Perhaps rename rb.h to rbtree.h, since cleaning-up..

static executables (such as newer versions of /sbin/ldconfig)
require this to work properly. since static executables
also don't have a PT_PHDR entry, use the same heuristic as
linux does to provide a value for AT_PHDR in this case.

case a race condition exists which can cause this

(looks harmless because it applies to zero-initialized memory, so
LIST_INIT() is a no-op)
-wrong loop count in reply misses a hash bucket (PR kern/43827)

to the PR above)
if size 0 and starting after the text segments, if no data segment was
found. Unbreaks sbrk on platforms where all loaded segments are
executable (PR 43817). The cast of executable segments after data
segments is left out for now.
churn creates interesting code.
Fixes open(O_CREAT|O_TRUNC) on at least tmpfs and nfs to not fail
with ENOENT due to a racy removal of the newly created file.
Caught, as most bugs these days are, by a test run.
- since the size is unsigned, don't check just that it is > 0, but limit
it to the MAXSSIZ
- if the stack size is reduced because of aslr, make sure we reduce the
actual allocation by the same size so that the size does not wrap around.

kernconfig_mutex. Update module subsystem to use this mutex rather than
its own internal (non-recursive) mutex. Make module_autoload() do its
own locking to be consistent with the rest of the module_xxx() calls.
Update module(9) man page appropriately.

necessary for vget() to handle VI_INACTNOW as a special case. Remove this
check and its support in vrelel().
Getting another reference while the freelist is locked is an error. Replace
the check with a KASSERT.
