Modified files:
sys/sys resourcevar.h
sys/kern kern_resource.c
Log:
- Use wait-free method to manage ui_sbsize and ui_proccnt fields in the
uidinfo structure. This entirely removes contention observed on the
ui_mtxp mutex (as it is now gone).
- Convert the uihashtbl_mtx mutex to a rwlock, as most of the time we just
need to read-lock it.
