Linux-2.6.12-rc2v2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!

8 | =========== | ||

10 | ufstype=type_of_ufs | ||
11 | UFS is a file system widely used in different operating systems. | ||
12 | The problem are differences among implementations. Features of | ||
13 | some implementations are undocumented, so its hard to recognize | ||
14 | type of ufs automatically. That's why user must specify type of | ||
15 | ufs manually by mount option ufstype. Possible values are: | ||
16 | |||
17 | old old format of ufs | ||
18 | default value, supported as read-only | ||
19 | |||
20 | 44bsd used in FreeBSD, NetBSD, OpenBSD | ||
21 | supported as read-write | ||
22 | |||
23 | ufs2 used in FreeBSD 5.x | ||
24 | supported as read-only | ||
25 | |||
26 | 5xbsd synonym for ufs2 | ||
27 | |||
28 | sun used in SunOS (Solaris) | ||

51 | ================= | ||
52 | |||
53 | There is still bug in reallocation of fragment, in file fs/ufs/balloc.c, | ||
54 | line 364. But it seems working on current buffer cache configuration. | ||
