6b51bdc17c Lock buffers with B_BUSY between data checksum calculation and write, so 
some other process doesn't change the data after it was checksummed.

1cacaa295f Change lfs_sb_cksum to use offsetof() instead of an inlined version. 
Fix lfs_vref/lfs_vunredf to ignore VXLOCKed vnodes that are also being
flushed.

Improve the debugging messages somewhat.

d2397ac5f7 completely remove Mach VM support. all that is left is the all the 
header files as UVM still uses (most of) these.

e1c9a578a8 New CHANGES files that describes briefly all nontrivial changes made to 
the LFS since the 4.4lite2 code was merged into NetBSD.

TODO updated to remove everything marked DONE in 4.4, and add in a list
of more current things to do.

Get rid of comments about the cleaner syscall code and missing fragment
support from README.

462ac41141 if an mfs i/o is successful, set b_resid to 0.

1b8f5ea3c3 New sources should leave the LFS in a more-or-less working state. Changes 
include:

	- DIROP segregation is enabled, and greater care is taken
	  to make sure that a checkpoint completes.  Fsck is not
	  needed to remount the filesystem.
	- Several checks to make sure that the LFS subsystem does not
	  overuse various resources (memory, in particular).
	- The cleaner routines, lfs_markv in particular, are completely
	  rewritten.  A buffer overflow is removed.  Greater care is taken
	  to ensure that inodes come from where lfs_cleanerd say they come
	  from (so we know nothing has changed since lfs_bmapv was called).
	- Fragment allocation is fixed, so that writes beyond end-of-file
	  do the right thing.

00d7241e81 Don't check fs_bsize before the superblock has been swapped if needed.

862a56e88b Modify vfsops to seperate vfs_fhtovp() into two routines. vfs_fhtovp() now 
only handles the file handle to vnode conversion, and a new call,
vfs_checkexp(), performs the export verification.

there also.  this avoids overflowing the link count.

dc306354b0 Move the bswap functions from libutil to libc (this bups the 
minor of libc and the major of libutil). For little-endian architectures
merge the bnswap() assembly versions with nto* and hton* using symbols
aliasing. Use symbol renaming for the bswap function in this case to avoid
namespace pollution.
Declare bswap* in machine/bswap.h, not machine/endian.h. For little-endian
machines, common code for inline macros go in machine/byte_swap.h
Sync libkern with libc.
Adjust #include in kernel sources for machine/bswap.h.

b10470bc11 #include opt_uvm.h only if _KENREL and !_LKM 
Make ext2fs_init() call ufs_init(). it was doing the init by itself,
testing for extern done != 0. This bug was hidden by the fact that
ext2fs_init() is called before ffs_init().

XXX MFS also comes in here for inodes, and used a different malloc type,

7e0aabe421 Remove v_type != DIR check. First, vn_readdir already does 
this check, before calling VOP_READDIR.  Second, vn_readdir
returns a different error even.  Finally, some FS's might
want to write their directories into files that look like
BSD directories and then have ufs_readdir parse them.
