lfs currently has the following headers:
lfs.h - on-disk structures and stuff needed for userlevel tools
lfs_inode.h - additional restricted materials for userlevel tools
that operate the fs (newfs_lfs, fsck_lfs, lfs_cleanerd)
lfs_kernel.h - stuff needed only in the kernel
and the following legacy headers that are expected to be mopped up and
folded into one of the above:
lfs_extern.h - function prototypes
ulfs_bswap.h - endian-independent support
ulfs_dinode.h - now contains very little
ulfs_dirhash.h - dirhash support
ulfs_extattr.h - extattr support
ulfs_extern.h - more function prototypes
ulfs_inode.h - assorted kernel-only declarations
ulfs_quota.h - quota support
ulfs_quota1.h - more quota support
ulfs_quota2.h - more quota support
ulfs_quotacommon.h - more quota support
ulfsmount.h - legacy copy of ufsmount material
