CVS commit: src/sbin/fsck_ffs

["Christos Zoulas" <christos%netbsd.org@localhost>]

Module Name:    src
Committed By:   christos

Modified Files:
        src/sbin/fsck_ffs: dir.c fsck.h fsck_ffs.8 main.c

Log Message:
Add a -z flag to zero out the up to 4 bytes of padding in directory entry
names (including the terminating NUL), as well as directory entries with
extra free space (d->d_reclen > UFS_DIRSIZ(d)).

Inspired from FreeBSD:
    https://svnweb.freebsd.org/base?view=revision&revision=347066

While the kernel has been fixed to deal with the padding bytes (new
kernels will correctly zero out all the padding after the name), it
appears that there is still an issue with directory entries with extra
free space, since a newly created and populated filesystem gets modified
with "fsck_ffs -z".
