do not need to check for root device as blockcheck has done so already;
complain when presented with a block device

initialize inplast (from shumway@sun.com)

allocate hash headers and sort list

convert to BSD only copyright

lint and other aesthetic cleanups

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

ANSI C cleanups from Torek

new include file locations engendered by vnodes

recalculate size of cylinder group block when changing formats

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

conversion (in either direction) is only done when requested with -c

conversion between static and dynamic cylinder group tables;
force write of last alternate super block when adding new constants
(to avoid comparison errors during normal super block checking)

recover from trashed summary information

make ANSI C compatible

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

huh? where did this come from?

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

make fixing interleave non-fatal

allow fsck to proceed even when not setting default psect and interleave

update disk labels to ioctl's; check the file the user specified!;
don't try to check "." if a named file doesn't exist;
don't check spare constants in superblock against alternate;
make the "TRASHED

update disk labels to ioctl's; check the file the user specified!;
don't try to check "." if a named file doesn't exist;
don't check spare constants in superblock against alternate;
make the "TRASHED VALUES" message understandable

use SBOFF instead of SBLOCK

intuit the appropriate DEV_BSIZE from fsbtodb macro

must copy fs_npsect and fs_interleave to cope for old file systems

add sanity checks for new values used in calculating rotational layout

reorganize to allow use of disk labels to search for alternate
super-blocks when the standard super-block is unusable
