7ef47eec4c ext2fs relies on UFS support code, and as a result also requires
extattr.h to be included.  This fixes the broken ext2fs build as of
the import of extattr code.

Also added $FreeBSD: $ to a couple of files that didn't have them,
without which I couldn't commit this fix.

a64ed08955 Introduce extended attribute support for FFS, allowing arbitrary
(name, value) pairs to be associated with inodes.  This support is
used for ACLs, MAC labels, and Capabilities in the TrustedBSD
security extensions, which are currently under development.

In this implementation, attributes are backed to data vnodes in the
style of the quota support in FFS.  Support for FFS extended
attributes may be enabled using the FFS_EXTATTR kernel option
(disabled by default).  Userland utilities and man pages will be
committed in the next batch.  VFS interfaces and man pages have
been in the repo since 4.0-RELEASE and are unchanged.

o ufs/ufs/extattr.h: UFS-specific extattr defines
o ufs/ufs/ufs_extattr.c: bulk of support routines
o ufs/{ufs,ffs,mfs}/*.[ch]: hooks and extattr.h includes
o contrib/softupdates/ffs_softdep.c: extattr.h includes
o conf/options, conf/files, i386/conf/LINT: added FFS_EXTATTR

o coda/coda_vfsops.c: XXX required extattr.h due to ufsmount.h
(This should not be the case, and will be fixed in a future commit)

Currently attributes are not supported in MFS.  This will be fixed.

e4649cfac3 Change the write-behind code to take more care when starting
async I/O's.  The sequential read heuristic has been extended to
    cover writes as well.  We continue to call cluster_write() normally,
    thus blocks in the file will still be reallocated for large (but still
    random) I/O's, but I/O will only be initiated for truely sequential
    writes.

    This solves a number of annoying situations, especially with DBM (hash
    method) writes, and also has the side effect of fixing a number of
    (stupid) benchmarks.

21144e3bf1 Remove B_READ, B_WRITE and B_FREEBUF and replace them with a new
field in struct buf: b_iocmd.  The b_iocmd is enforced to have
exactly one bit set.

B_WRITE was bogusly defined as zero giving rise to obvious coding
mistakes.

Also eliminate the redundant struct buf flag B_CALL, it can just
as efficiently be done by comparing b_iodone to NULL.

Should you get a panic or drop into the debugger, complaining about
"b_iocmd", don't continue.  It is likely to write on your disk
where it should have been reading.

This change is a step in the direction towards a stackable BIO capability.

A lot of this patch were machine generated (Thanks to style(9) compliance!)

15e549f668 Bug fixes for currently harmless bugs that could rise to bite
the unwary if the code were called in slightly different ways.

1) In ufs_bmaparray() the code for calculating 'runb' will stop one block
short of the first entry in an indirect block. i.e. if an indirect block
contains N block numbers b[0]..b[N-1] then the code will never check if
b[0] and b[1] are sequential. For reference, compare with the equivalent
code that deals with direct blocks.

2) In ufs_lookup() there is an off-by-one error in the test that checks
if dp->i_diroff is outside the range of the the current directory size.
This is completely harmless, since the following while-loop condition
'dp->i_offset < endsearch' is never met, so the code immediately
does a second pass starting at dp->i_offset = 0.

3) Again in ufs_lookup(), the condition in a sanity check is wrong
for directories that are longer than one block. This bug means that
the sanity check is only effective for small directories.

d68084cd89 Merged changes in ext2_fs.h between Linux 1.2.2 and Linux 2.3.35. The
main changes are:
- many things are more dynamic; e.g., the inode size is a new parameter
  in the superblock instead of a constant.
- extensions are controlled by new flags in the superblock.
- directory entries may have a file type field.
These changes are not used yet, except for a spelling change which affects
ext2_cnv.c

c9fbb5bc2c Merged cosmetic changes from the initial import on the vendor branch
(mainly things that were lost or misformatted in a different way by
moving them to ext2_fs_i.h and back, and ifdefs for user mode that

8e19715af3 Use an ifdef in ext2_fs.h instead of a bogus separate file (ext2_fs_i.h)
to avoid the namespace problems caused by <ufs/ufs/inode.h> #defining
i_mode, etc.

ext2_fs_i.h had nothing to do with the Linux version.  It was a small
part of the Linux version of ext2_fs.h (the part that declares extra
in-core fields for an inode).  We don't need it because we use the
ufs in-core inode for the extra fields.
