FIXED-TERM Chen Ian (BT-CO/QMM5)	8d4ff0bc1e	fix typos in user/usertest.c & kernel/log.c	2021-08-31 14:10:14 -04:00
Frans Kaashoek	b4c2851bb3	Be principled: acquire lock first	2020-11-05 19:50:46 -05:00
Robert Morris	548ffc97e1	don't unpin if recovering -- the resulting negative refcnt suppresses next unpin	2020-10-05 19:30:27 -04:00
Frans Kaashoek	2501560cd6	Cosmetic cleanup: fsinit reads sb and calls loginit. initialize icache ... 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.	2019-08-18 14:35:11 -04:00
Frans Kaashoek	f37a3e3964	Make pin/unpin explicit	2019-07-30 08:54:43 -04:00
Frans Kaashoek	5304310452	Remove B_DIRTY ... Use refcnt to pin blocks into the cache Replace flags/B_VALID with a boolean field valid Use info[id].status to signal completion of disk interrupt Pass a read/write flag to virtio_disk_rw	2019-07-29 17:33:16 -04:00
Robert Morris	5753553213	separate source into kernel/ user/ mkfs/	2019-06-11 09:57:14 -04:00
