Age	Commit message (Collapse)	Author	Files	Lines
2006-08-13	namei returns locked parent dir inode for create / unlink	rtm	1	-8/+12
	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
2006-08-12	fstat	kaashoek	1	-0/+13
	primitive ls
2006-08-10	interrupts could be recursive since lapic_eoi() called before rti	rtm	1	-0/+6
	so fast interrupts overflow the kernel stack fix: cli() before lapic_eoi()
2006-08-10	printf	kaashoek	1	-1/+7
	convert userfs to use printf bfree ifree writei start on unlink
2006-08-09	devsw	kaashoek	1	-0/+4
	checkpoint: write(fd,"hello\n",6) where fd is a console dev almost works
2006-08-08	fix race in holding() check in acquire()	rtm	1	-0/+7
	give cpu1 a TSS and gdt for when it enters scheduler() and a pseudo proc[] entry for each cpu cpu0 waits for each other cpu to start up read() for files
2006-07-29	open()	rtm	1	-0/+2

2006-07-17	nitpicks	rsc	1	-2/+2

2006-07-16	more name cleanup	rsc	1	-9/+7

2006-07-16	remove non-idiomatic increment/decrement	rsc	1	-1/+1

2006-07-16	Rename fd_reference to more suggestive fd_incref.	rsc	1	-1/+1
	(Fd_reference sounds like it might just return the ref count.)
2006-07-12	no more big kernel lock	rtm	1	-0/+25
	succeeds at usertests.c pipe test
2006-07-01	swtch saves callee-saved registers	rtm	1	-13/+17
	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	1	-0/+80
