2006-09-07	one regression test program	kaashoek

2006-09-06	standardize various * conventions	rsc

2006-08-29	prune unneeded panics and debug output	rtm

2006-08-29	i broke sbrk, fix it	rtm

2006-08-25	kill user process when it generates an unhandled trap (e.g., 13)	kaashoek
	fix bug in test code of malloc
2006-08-24	bug in sbrk	kaashoek
	test malloc
2006-08-19	chdir	kaashoek
	cd in shell nits in mkdir, ls, etc.
2006-08-15	no more proc[] entry per cpu for idle loop	rtm
	each cpu[] has its own gdt and tss no per-proc gdt or tss, re-write cpu's in scheduler (you win, cliff) main0() switches to cpu[0].mpstack
2006-08-13	namei returns locked parent dir inode for create / unlink	rtm
	don't hold fd table lock across idecref() (latter does block i/o) idecref calls iput() in case last ref -> freeing inode dir size is 512 * # blocks, so readi/writei &c work unlink deletes dirent even if ip->nlink > 0
2006-08-13	link()	rtm

2006-08-12	LRU disk cache replacement	rtm

2006-08-12	buffer cache, fifo replacement	rtm

2006-08-12	mknod set nlink = 1	rtm
	usertests for concurrent create/delete, and read() after unlink()
2006-08-12	fix getblk to actually lock the block	rtm
	no more cons_put system calls usertests tests two processes writing files
2006-07-28	exec arguments	rtm

2006-07-17	nitpicks	rsc

2006-07-16	Add user.h for prototypes.	rsc
	Add cons_puts for cleaner output.
2006-07-15	no more recursive locks	rtm
	wakeup1() assumes you hold proc_table_lock sleep(chan, lock) provides atomic sleep-and-release to wait for condition ugly code in swtch/scheduler to implement new sleep fix lots of bugs in pipes, wait, and exit fix bugs if timer interrupt goes off in schedule() console locks per line, not per byte
2006-07-12	passes both usertests	rtm
	exit had acquire where I meant release swtch now checks that you hold no locks
2006-07-12	cvs add spinlock.h	rtm
	fix race in schedule()
2006-07-12	no more big kernel lock	rtm
	succeeds at usertests.c pipe test
2006-07-11	give each cpu its own clock, so that preemption works on cpu 1	rtm

2006-07-11	pre-empt both user and kernel, in clock interrupt	rtm
	usertest.c tests pre-emption kill()
2006-07-01	swtch saves callee-saved registers	rtm
	swtch idles on per-CPU stack, not on calling process's stack fix pipe bugs usertest.c tests pipes, fork, exit, close
2006-06-27	file descriptors	rtm
	pipes
