cvs add spinlock.h fix race in schedule() 2006-07-12 11:10:25 +02:00			`struct spinlock {`
open() 2006-07-29 11:35:02 +02:00			`char *name;`
add uint and standardize on typedefs instead of unsigned 2006-07-17 03:52:13 +02:00			`uint locked;`
add ide_lock for sleep 2006-07-17 07:00:25 +02:00			`int cpu;`
interrupts could be recursive since lapic_eoi() called before rti so fast interrupts overflow the kernel stack fix: cli() before lapic_eoi() 2006-08-11 00:08:14 +02:00			`uint pcs[10];`
cvs add spinlock.h fix race in schedule() 2006-07-12 11:10:25 +02:00			`};`
