Some more info related to ffs_isblock():
(kgdb) p got - run + i
$2 = 2160
(kgdb) p i
$3 = 1
(kgdb) p len
$4 = 4
(kgdb) p fs->fs_frag
$5 = 8
(kgdb) p (unsigned char *)blksfree[got - run + i]
$7 = (unsigned char *) 0x3fffff0f <Address 0x3fffff0f out of bounds>
>From ffs_subr.c:
int
ffs_isblock(fs, cp, h)
struct fs *fs;
unsigned char *cp;
ufs_daddr_t h;
{
unsigned char mask;
switch ((int)fs->fs_frag) {
case 8:
return (cp[h] == 0xff);
...
}
