no longer need to include time.h, vnode.h, and inode.h; just include dinode.h

POSIX signals

ANSI C cleanups from Torek

free up buffer space after use

new include file locations engendered by vnodes

must be sure to always convert b_bno to disk block (db) units

add firewall to check for lost buffers; fine tune cache statistics

expand from three static buffer to a dynamic buffer pool;
initial sizing of the buffer pool is 128K (For 8K fs == 16 buffers)

fix alternate superblock location again; don't offer to rewrite
standard superblock if we haven't found a good one yet; standardize units
for -b (sectors! as before); kernel may change fs_dbsize

use physical sector size for partial buffer reads;
-n implies "yes" answer for "CONTINUE?"

eliminate dbtob macro (which uses DEV_BSIZE)

use SBOFF instead of SBLOCK

intuit the appropriate DEV_BSIZE from fsbtodb macro

must zero the buffer

must do lseek after read or write failure

be more persistent in trying to read directories;
add FOUND return status for routines called from dirscan

allow a single sigquit to force exit(2) after completing checks
if preening

Add copyright

persist in writing back bad sectors; be more informative about the errors

check for improper directory offsets; recover gracefully from read errors

must remember to flush out cylinder group block when done

calc and print out pathname of offending hard links to directories

expand lost+found when running out of space

code reorganization and cleanup
