xv6 code. Lab submission instructions etc. are likely going to be more MIT 6.828 specific.

2019-08-19Avoid rereading the superblock in bfreeDan Cross1-1/+0
The superblock is read when the first process returns to userspace (via the call to `iinit` from the first invocation of `forkret`, when `first` is still set to 1) and cached in a global; it is treated as immutable from that point on. There is no reason to re-read it in bfree. Removing this call seems to have simply been missed in 8320d61b when this general area was last touched. Remove it now to avoid potential confusion.

2019-08-19Removed unused `dirlookup` argument in `create`Dan Cross1-2/+1
The `off` argument to `dirlookup` is optional. It was not being used in the `dirlookup` call in `create`, so pass NULL instead and delete the unused local. Signed-off-by: Dan Cross <cross@gajendra.net>
2019-08-18Cosmetic cleanup: fsinit reads sb and calls loginit. initialize icacheFrans Kaashoek5-18/+21
in main.c and don't make it disk specific; the icache is shared. This doesn't matter since we have only one disk, but conceptually cleaner and maybe helpful to students for mount lab.

2019-08-12Draft mount/umount lab as an alternative lab for fs.htmlFrans Kaashoek1-0/+198
fs.html should perhaps be split in small homeworks as in previous years in preparation for lectures and/or as demos during lecture.

several disks (e.g., in a mount lab).

they don't have to modify alarmtest.c, so we can use the original version to test, to make it harder to cheat.
