Use the dedicated reference counting routines.
Change the type of struct vmspace::vm_refcnt and struct vm_map::ref_count
to volatile.
Remove the unnecessary vm->vm_map.misc_lock locking in process_domem().

the list of routines that need to be called for setting up sysctl
variables. This worked great for all code included in the kernel
itself, but didn't deal with modules that want to create their own
sysctl data. So, we ended up with a lot of #ifdef _MODULE blocks
so modules could explicitly call their setup functions when loaded
as non-built-in modules.
So today, we complete the task that was started so many years ago.
When modules are loaded, after we've called xxx_modcmd(INIT...) we
check if the module contains its own __link_set_sysctl_funcs, and
if so we call the functions listed. We add a struct sysctllog member
to the struct module so we can call sysctl_teardown() when the module
gets unloaded. (The sequence of events ensures that the sysctl stuff
doesn't get created until the rest of the module's init code does any
required memory allocation.)
So, no more need to explicitly call the sysctl setup routines when
built as a loadable module.
and retry the command. Start with a small openings number and let scsipi
request to grow it up to the current send window.
Adjust ccb and pdu counts to avoid ressource shortages. These are still
very ad-hoc numbers, but seem to be sufficient for a Gigabit link.
Use separate condvar for PDU pool and add counter to help debugging.
Revert setting PDU disposition to UNUSED before freeing. free_pdu
uses this as a flag to detect already returned PDUs.
Add reference counter for open commands to defer unmapping a session
that would lead to crashes in scsipi.
Move session cleanup to cleanup thread.
Use get_sernum to retrieve current serial number where possible and
make it check for immediate commands itself.
Adjust debug output.
