cvs add spinlock.h fix race in schedule() 2006-07-12 09:10:25 +00:00			`struct spinlock {`
open() 2006-07-29 09:35:02 +00:00			`char *name;`
add uint and standardize on typedefs instead of unsigned 2006-07-17 01:52:13 +00:00			`uint locked;`
add ide_lock for sleep 2006-07-17 05:00:25 +00:00			`int cpu;`
interrupts could be recursive since lapic_eoi() called before rti so fast interrupts overflow the kernel stack fix: cli() before lapic_eoi() 2006-08-10 22:08:14 +00:00			`uint pcs[10];`
