hash tables used in the sleep queue and turnstile code. Each option adds
a sysctl tree under debug containing the maximum depth of any bucket in
the hash table as well as a separate node for each bucket (or chain)
containing the current depth and maximum depth for that bucket.
vm objects shadowing source in vm_object_shadow(). This closes a race where
vm_object_collapse() could be called with a partially uninitialized object
argument causing symptoms that looked like hardware problems, e.g. signal 6,
10, 11 or a /bin/sh busy-waiting for a nonexistant child process.
the queue has been removed from the global taskqueue_queues list. This
removes the need for the draining queue hack.
- Allow taskqueue_run() to be called with the taskqueue mutex held. It
can still be called without the lock for API compatiblity. In that case
it will acquire the lock internally.
- Don't lock the individual queue mutex in taskqueue_find() until after the
strcmp as the global queues mutex is sufficient for the strcmp.
- Simplify taskqueue_thread_loop() now that it can hold the lock across
taskqueue_run().

and bump all of the taskqueue swi's to 6. This gives callouts higher
priority than taskqueue tasks and gives all taskqueue tasks the same
priority.
Discussed with: bde
applied to their permissions. Just calculate the
default dir mode once and use it consistently, rather than
trying to remember to calculate it everywhere it's needed.
than a a stack-limited list. This removes the artifical limit on s/g list
size.
cvs: ----------------------------------------------------------------------
* Don't change the umask; the library now ignores the umask if
you set EXTRACT_PERM
* Set the EXTRACT_ACL and EXTRACT_FFLAGS bits (used to be
controlled by EXTRACT_PERM).
* Rename some variables/functions/etc to try to make things clearer.
* Add separate flags to control fflag/acl restore
* Collect metadata restore into a single function for clarity
* Propagate errors in metadata restore back out to the client
* Fix some places where errors were being returned when they
shouldn't and vice-versa
* Modes are now always restored; ARCHIVE_EXTRACT_PERM just controls
whether or not umask is obeyed.
* Restore suid/sgid bits only if user/group matches archive
* Cache the last stat results to try to reduce the number of stat calls
archive_entry.
Update the Makefile MLINKS and manpage to bring it up-to-date with
the current status of archive_entry. At least the manpage actually
lists all of the functions now, even if it doesn't really yet explain
them all.
