Modified files:
sys/dev/md md.c
Log:
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.
