data type, and running time of its I/O operations.

fdc61a888d Fix the check in dircheck() on namlen.
The value of namlen is copied from on-disk d_namlen, which is a 8-bit
unsigned integer which can never exceed MAXNAMLEN (255) so the test is
always true.  Moreover, UFS does not allow d_namelen being zero.

Change namlen from u_int to u_int8_t, and replace the unneeded test
with a useful test.

af6726e657 Eliminate linked list used to track inodes with an initial link
count of zero and instead encode this information in the inode state.
Pass 4 performed a linear search of this list for each inode in
the file system, which performs poorly if the list is long.

d6ad008082 Change the default mode for lost+found from 01777 to 0700. The
original intention of the less restrictive permissions was to allow
users to move or delete recovered files that they own. However, it
is better to not create world-writable directories by default; the
administrator can always pre-create lost+found if different permissions
are desired.

1c85e6a35d This commit adds basic support for the UFS2 filesystem. The UFS2
filesystem expands the inode to 256 bytes to make space for 64-bit
block pointers. It also adds a file-creation time field, an ability
to use jumbo blocks per inode to allow extent like pointer density,
and space for extended attributes (up to twice the filesystem block
size worth of attributes, e.g., on a 16K filesystem, there is space
for 32K of attributes). UFS2 fully supports and runs existing UFS1
filesystems. New filesystems built using newfs can be built in either
UFS1 or UFS2 format using the -O option. In this commit UFS1 is
the default format, so if you want to build UFS2 format filesystems,
you must specify -O 2. This default will be changed to UFS2 when
UFS2 proves itself to be stable. In this commit the boot code for
reading UFS2 filesystems is not compiled (see /sys/boot/common/ufsread.c)
as there is insufficient space in the boot block. Once the size of the
boot block is increased, this code can be defined.

Things to note: the definition of SBSIZE has changed to SBLOCKSIZE.
The header file <ufs/ufs/dinode.h> must be included before
<ufs/ffs/fs.h> so as to get the definitions of ufs2_daddr_t and
ufs_lbn_t.

Still TODO:
Verify that the first level bootstraps work for all the architectures.
Convert the utility ffsinfo to understand UFS2 and test growfs.
Add support for the extended attribute storage. Update soft updates
to ensure integrity of extended attribute storage. Switch the
current extended attribute interfaces to use the extended attribute
storage. Add the extent like functionality (framework is there,
but is currently never used).

It does not help modern compilers, and some may take some hit from it.
(I also found several functions that listed *every* of its 10 local vars with
 "register" -- just how many free registers do people think machines have?)

bf58d635ba Fix a large number of -Wall, -Wformat and -W compiler warnings.
These were mainly missing casts or wrong format strings in printf
statements, but there were also missing includes, unused variables,
functions and arguments.

The choice of `long' vs `int' still seems almost random in a lot
of places though.

7578c6ab98 Additions to run checks on live filesystems. This change will not
affect current systems until fsck is modified to use these new
facilities. To try out this change, set the fsck passno to zero
in /etc/fstab to cause the filesystem to be mounted without running
fsck, then run `fsck_ffs -p -B <filesystem>' after the system has
been brought up multiuser to run a background cleanup on <filesystem>.
Note that the <filesystem> in question must have soft updates enabled.

91ea161570 If the lost+found directory is created by fsck, it will do a cacheino()
which sets the inoinfo's i_parent and i_dotdot to 0, but they never get
set to ROOTINO. This means that propagate will never find lost+found and
its descendents, subdirectories will remain DSTATE (instead of DFOUND)
even though they *are* correctly linked in, and pass4.c will try to
clear them unsuccessfully, thinking that there is no link count from the
DSTATE directory's parent. The result is that you need to run fsck twice
and get link count increasing errors (which are unexpected and fatal
when running in preen mode). The fix is to set i_parent and i_dotdot to
"parent" after the second cacheino() call in dir.c:allocdir().

and /usr/include/ufs/ffs/fs.h (1.16) as of July 4, 2000 or later.

Subject: Fix for annoying fsck bug
Date: Wed, 24 Jan 1996 13:33:29 -0700 (MST)

The following small diff fixes the annoying fsck bug that causes it to
need to be run twice to end up with correct reference counts for inodes
for directories that had subdirectories relocated into the lost+found
directory.

I found the need to rerun *extremely* annoying.  This fix causes the
count to be correctly adjusted later in pass 4 by correctly stating
the parent reference count.

Note that the parent reference count is incremented when the directory
entry is made (for ".."), but is not really there in the case of a
directory that does not make an entry in its parent dir.

This can be tested by waiting for the inode sync after cd'ing from a
shell into a test fs.  Then you "mkdir xxx yyy zzz", wait a second,
and hit the machine reset button.

2) pass1.c: When doing -c2 conversion, do secsize reads for a symlink -
   not doing so was causing the conversion to fail because the device
   driver can't deal with short reads.
