tron 057ae88da9 Don't include "opt_uvm.h" any more. 1999-03-24 11:05:31 +00:00
mrg d2397ac5f7 completely remove Mach VM support. all that is left is the all the
header files as UVM still uses (most of) these.

perseant 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.

chs 462ac41141 if an mfs i/o is successful, set b_resid to 0.
this allows the vnd driver to work on mfs files.

perseant 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.

wrstuden 862a56e88b Modify vfsops to seperate vfs_fhtovp() into two routines. vfs_fhtovp() now

vfs_checkexp(), performs the export verification.

bouyer 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.

ext2fs_init() is called before ffs_init().

* in the read vnode operator, check for IO_SYNC being set in the ioflag and
  synchronously update the file's meta-data if appropriate.
* in the write vnode operator, update the appropriate checks for IO_SYNC being
  set in the ioflag to reflect that IO_DSYNC is now inclusive-or'ed into
  IO_SYNC, and require all IO_SYNC bits to be set for operations defined by
  synchronized I/O file integrity completion but not by synchronized I/O data
  integrity completion.

cgd 651b44e211 Rework the way kernel include files are installed. In the new method,
as with user-land programs, include files are installed by each directory
in the tree that has includes to install.  (This allows more flexibility
as to what gets installed, makes 'partial installs' easier, and gives us
more options as to which machines' includes get installed at any given
time.)  The old SYS_INCLUDES={symlinks,copies} behaviours are _both_
still supported, though at least one bug in the 'symlinks' case is
fixed by this change.  Include files can't be build before installation,
so directories that have includes as targets (e.g. dev/pci) have to move
those targets into a different Makefile.

bouyer 091dafd39f Add support for reading/writing FFS in non-native byte order, conditioned
to "options FFS_EI". The superblock and inodes (without blk addr) are
byteswapped at disk read/write time, other metadatas are byteswapped
when used (as they are acceeded directly in the buffer cache).
This required the addition of a "um_flags" field to struct ufsmount.
ffs_bswap.c contains superblock and inode byteswap routines also used
by userland utilities.
