This commit was manufactured to restore the state of the 5.3-RELEASE image.

Fix the alpha tinderbox. The alpha specific bitops used by the bitmap

2003-10-29T07:35:53+00:00

code has the typical branch prediction detour, which creates cross-
section branches. A LINT kernel is apparently large enough nowadays
that the .text and .text2 sections cannot always be layed-out so that
branches between them reach.
The fix is to stop using the alpha-specific bitops and instead use
the portable implementation used by all platforms other than alpha
and i386.

Change of plans: Add ext2_bitops.h with generic and portable

2003-08-25T01:39:47+00:00

implementations. Use those on platforms that don't have MD
headers. Remove the ia64 MD header. We're going to use the C
implementation there.

Add compilation support for extfs on ia64, primarily to support LINT.

2003-08-23T03:58:11+00:00

The functions in ia64-bitops.h merely call panic() for now. They need
to be implemented some day, just not today.

Fix typos, mostly s/ an / a / where appropriate and a few s/an/and/

2002-12-30T21:18:15+00:00

Add FreeBSD Id tag where missing.

Complete the separation of ext2fs from ufs by copying the remaining

2002-05-16T19:08:03+00:00

shared code and converting all ufs references. Originally it may
have made sense to share common features between the two filesystems,
but recently it has only caused problems, the UFS2 work being the
final straw.

All UFS_* indirect calls are now direct calls to ext2_* functions,
and ext2fs-specific mount and inode structures have been introduced.

Put the bits in place for Alpha support for ext2. Not tested.

Support filesystems with the not-so-new "sparse_superblocks" feature.

2000-11-03T16:41:48+00:00

When this feature is enabled, mke2fs doesn't necessarily allocate a
super block and its associated descriptor blocks for every group.
The (non-)allocations are reflected in the block bitmap.  Since the
filesystem code doesn't write to these blocks except for the first
superblock, all it has to do to support them is to not count them in
ext2_statfs() and not attempt to check them at mount time in
ext2_check_blocks_bitmap() (the check has never been enabled in
FreeBSD anyway).

Weaken a bogus dependency on in by #ifdef'ing

the offending inline function (BUF_KERNPROC) on it being #included
already.

I'm not sure BUF_KERNPROC() is even the right thing to do or in the
right place or implemented the right way (inline vs normal function).

Remove consequently unneeded #includes of

 is now a prerequisite for  but it shall
not be made a nested include according to bdes teachings on the
subject of nested includes.

Diskdrivers and similar stuff below specfs::strategy() should no
longer need to include  unless they need caching of data.

Still a few bogus uses of struct buf to track down.
