Poul-Henning Kamp 9b00ca1961 Fix configuration locking in MD. ... Remove md_mtx. Remove GIANT from the mdctl device driver and avoid DROP_GIANT, PICKUP_GIANT and geom events since we can call into GEOM directly now. Pick up Giant around vn_close(). Apply an exclusive sx around mdctls ioctl and preloading to protect lists etc.. Don't initialize our lock (md_mtx or md_sx) from a SYSINIT when there is a perfectly good pair of _fini/_init functions to do it from. Prune any final fractional sector from the mediasize to keep GEOM happy. Cleanups: Unify MDIOVERSION check in (x)mdctlioctl() Add pointer to start() routine to softc to eliminate a switch{} Inline guts of mddetach(). Always pass error pointer to mdnew(), simplify implementation.		2005-09-19 06:55:27 +00:00
