8f359bc68c Quick fix for not being able to sync all the buffers in boot() if
an ext2fs file system is mounted.  The soft update changes added
a check for B_DELWRI buffers.  This exposed the complete brokenness
of the previous quick fix for failing syncs (PR 3571, committed on
1997/08/04).  Use a new buffer flag B_DIRTY and don't abuse B_DELWRI.
B_DIRTY buffers are still written too late, as broken in the previous
fix.  This is fairly harmless, because B_DIRTY is only used for
bitmap buffers and fsck.ext2 can fix up the bitmaps perfectly.

Fixed a race in ULCK_BUF() (bremfree() was outside of the splbio()
section).

5fd549b62e Fix a problem with ext2fs so that filesystems mounted at reboot don't
keep ahold of buffers, and therefore leave filesystems dirty.  I haven't
been able to test, but the code compiles.  Those who run -current, please
test and report back!!!  (Sorry :-)).

996c772f58 This is the kernel Lite/2 commit. There are some requisite userland
changes, so don't expect to be able to run the kernel as-is (very well)
without the appropriate Lite/2 userland changes.

The system boots and can mount UFS filesystems.

Untested: ext2fs, msdosfs, NFS
Known problems: Incorrect Berkeley ID strings in some files.
		Mount_std mounts will not work until the getfsent
		library routine is changed.

c33a4405f7 Main code for the ext2fs filesystem. Please refer to the COPYRIGHT.INFO
file for GPL restrictions.  This code was ported to the BSD platform
by Godmar Back <gback@facility.cs.utah.edu> and specifically to FreeBSD
by John Dyson.  This code is still green and should be used with caution.
Additional changes to UFS necessary to make this code work will be commited
seperately.
