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().

142d8d2f40 Teach fsck about snapshot files. These changes should have no
effect on operation of fsck on filesystems without snapshots.
If you get compilation errors, be sure that you have copies of
/usr/include/sys/mount.h (1.94), /usr/include/sys/stat.h (1.21),
and /usr/include/ufs/ffs/fs.h (1.16) as of July 4, 2000 or later.

This exactly matches Kirks sources imported under the
Tag MCKUSICK2. These are as supplied by kirk with one small
change needed to compile under freeBSD.

Some FreeBSD patches will be added back, though many have been
added to Kirk's sources already.

780a5c1ec1 Merge from Lite2. Note that Lite2 has it's own filesystem clean check
skipping code that overrides ours sooner.  One should be eliminated,
but for now it works.

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.

9fef312289 Two fixes from the NetBSD group (Charles Hannum):
1) dir.c: get byte order right in mkentry()
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.
