thorpej a86d1f4891 Add a lock around the scheduler, and use it as necessary, including 
in the non-MULTIPROCESSOR case (LOCKDEBUG requires it).  Scheduler
lock is held upon entry to mi_switch() and cpu_switch(), and
cpu_switch() releases the lock before returning.

Largely from Bill Sommerfeld, with some minor bug fixes and
machine-dependent code hacking from me.

mycroft caf07dfa04 When unmounting, make sure to free the syncer vnode so that it can be reused. 2000-07-09 00:59:03 +00:00
simonb 45171aaef9 Delete redundant decls of vn_syncer_add_to_worklist(), syncdelay, 
filedelay, dirdelay and metadelay - they're in <sys/vnode.h>.

fvdl d901f6eae0 Be more careful to block bio interrupts for some data structures. There 
were at least a few missed cases where vp->v_{clean,dirty}blkhd were
unprotected since the softdep/trickle sync merge.

fvdl 0b1963121a Add Kirk McKusick's soft updates code to the trunk. Not enabled by 
default, as the copyright on the main file (ffs_softdep.c) is such
that is has been put into gnusrc. options SOFTDEP will pull this
in. This code also contains the trickle syncer.

Bump version number to 1.4O
