2006-09-06	struct fd -> struct file	rsc

2006-09-06	writeable => writable	rsc

2006-09-06	no /* */ comments	rsc

2006-09-06	standardize various * conventions	rsc

2006-08-20	compiling, but untested dup	kaashoek

2006-08-20	removed block system call	kaashoek
	renumber system calls (run gmake clean!) skeleton for dup system call
2006-08-13	fix iget() bug that allocated in-use inode[] entries	rtm

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
2006-08-12	fstat	kaashoek
	primitive ls
2006-08-10	interrupts could be recursive since lapic_eoi() called before rti	rtm
	so fast interrupts overflow the kernel stack fix: cli() before lapic_eoi()
2006-08-10	printf	kaashoek
	convert userfs to use printf bfree ifree writei start on unlink
2006-08-09	devsw	kaashoek
	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
	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

2006-07-17	nitpicks	rsc

2006-07-16	more name cleanup	rsc

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

2006-07-16	Rename fd_reference to more suggestive fd_incref.	rsc
	(Fd_reference sounds like it might just return the ref count.)
2006-07-12	no more big kernel lock	rtm
	succeeds at usertests.c pipe test
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
