was introduced. If you have a bus, say cardbus, that is derived from
a base-bus (say PCI), then ordinarily all PCI drivers would attach to
cardbus devices. However, there had been one exception: kldload
wouldn't work.
The problem is in devclass_add_driver. In this routine, all we did
was call to the pci device's BUS_DRIVER_ADDED routine. However, since
cardbus bus instances had a different devclass, none of them were
called.
The solution is to call all subclass devclasses, recursively down the
tree, of the class that was loaded. Since we don't have a 'children
class' pointer, we search the whole list of devclasses for a class
whose parent matches. Since just done a kldload time, this isn't as
bad as it sounds. In addition, we short-circuit the whole process by
marking those classes with subclasses with a flag. We'll likely have
to reevaluate this method the number of devclasses with subclasses
gets large.
This means we can remove the "cardbus" lines from all the PCI drivers
since we have no cardbus specific attach device attachments in the
tree.

not there is an audit record hung off of td_ar on the current thread.
Test this flag instead of td_ar when auditing syscall arguments or
checking for an audit record to commit on syscall return. Under
these circumstances, td_pflags is much more likely to be in the cache
(especially if there is no auditing of the current system call), so
this should help reduce cache misses in the system call return path.

locks: a global list/counter/generation counter protected by a new
mutex unp_list_lock, and a global linkage rwlock, unp_global_rwlock,
which protects the connections between UNIX domain sockets.
This eliminates conditional lock acquisition that was previously a
property of the global lock being held over sonewconn() leading to a
call to uipc_attach(), which also required the global lock, but
couldn't rely on it as other paths existed to uipc_attach() that
didn't hold it: now uipc_attach() uses only the list lock, which
follows the linkage lock in the lock order. It may also reduce
contention on the global lock for some workloads.
Add global UNIX domain socket locks to hard-coded witness lock
order.

A difference between the old and the new TTY layer is that the new
implementation does not perform any post-processing before returning
data back to userspace when calling read().
sh(1)'s read turns the TTY into a raw mode before calling select(). This
means that the first character will not receive any ICRNL processing.
Inherit this flag from the original terminal attributes.
Even though this issue is not present on RELENG_*, I'm MFCing it to make
sh(1) in jails behave better.
