An implementation of a log-structured filesystem into xv6.
Jon Morton, 2011.
current limitations:
- only one inode per block. this greatly simplifies the imap.
- the imap can only be one block long.
- writing to inodes cannot extend into indirect levels.
implementation order, as time allows:
[x] mkfs
[x] read-only lfs
[x] segment writing
[ ] segment cleaning
(original xv6 readme is in README.xv6)
