phase error on length computation (from Mark Dapoz md@bsc.no)

don't vgone the vnode in vcount if it is ours

cleanup code and comment on maximum number of processes (from cgd)

eradicate lofs

change chown(2) to follow symbolic links

lint

detect a suspected vget race with getnewvnode (and panic)

add procfs, union

typo

change struct recvfrom_args and struct sendto_args to take a size_t
as a length parameter

add support for user mounts (MNT_USER flag)

vref -> VREF

add support for union stacks into getdirentries.

add sysctl debug variable to enable/disable reallocblks

fix race in exit of session leader: if tty is revoked by spec_close
or other revoke while we wait for output to drain, ttyvp will be released
and null

first cut at improving cluster allocation

typo in printf

add definition for VOP_REALLOCBLKS

added union fs

removed usecount check in mount()

more ISOFS -> CD9660

when checking for MNT_ASYNC, make sure vp->v_mount is non-zero

ISOFS -> CD9660

disable MNT_ASYNC when doing sync and unmount

implement MNT_ASYNC
