src/sys/kern: subr_autoconf.c
src/sys/sys: device.h
Log Message:
autoconf(9): Prevent concurrent attach/detach and detach/detach.
- Use config_pending_incr/decr around attach. No need for separate
flag indicating device is still attaching. (dv_flags locking is also
incoherent.)
- Any config_pending now blocks config_detach.
- New dv_detaching exclusive lock for config_detach.
