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 <[email protected]>
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

several disks (e.g., in a mount lab).
2019-08-05add alarmtest.c to the repositoryRobert Morris2-84/+118
they don't have to modify alarmtest.c, so we can use the original version to test, to make it harder to cheat.
