proc.c:
as a consequence of the implementation of proc_kill,
any loop calling sleep should check for p->killed
and be able to break out with an error return.
it is better if you check *before* sleep.
can swap procdump up after proc_kill
and then have proc_exit and proc_wait on same sheet
sched -> switch2scheduler? or just switch?
factor out switching and scheduling code from process code
trap.c
if spin locks are ever held without cli,
trap should call yield() only if nlock == 0
ide.c: synchronous disk write -> polling disk write. search for
(a)synchronous; xv6 doesn't have asynchronous writes.
fs.c: split all name operations off in name.c? (starting with namei but move
wdir keep in fs.c)
pipe.c:
more comments?
comment how functions get called?
sysfile.c:
is the sys_exec picture upside down?
can sys_open and sys_exec be simplified any?
general:
sizeof parens?
