eliminate the fiction of NOQUAD

timeval => timespec in vattr and dinode

registerized vnodeop ops after vnode interface conversion

vnodeop argument macro expansion

vnode interface conversion

ap in lfs_truncate renamed inp because of name conflict with vnode arguments pointer "ap"

lint; inode times are now timevals

VOP_TRUNCATE now takes a cred argument

ensure proper types for local variables and parameters

delete unnecessary test; check depth in case drop out of loop early

move lfs_ifind into lfs_inode.c, it's only used in one place

during truncate, at INDIR/DIRECT boundary, decrement lbn by 1

use lfs_vflush for lfs_update; update the version number in truncate

fix bp usage, check lastseg in UPDATE_SEGUSE; from Carl

inline lfs_itod; make it handle unassiged disk addresses, this can
happen when the cleaner requests information about a dead file.

first cut at the truncate code

changes to make lfs_vget retrieve the IFILE inode like any other
inode

minor catchup before integrating lfs_truncate

slight reordering; update modrev time for NFS leases

LFS version 2; truncate must do vinvalbuf

proper setup for FIFO's

reorganization to move ufsmount ops to be vnode ops

cleanup ufs_vinit interface, don't typedef struct lfs now
UFS/FFS split for LFS version 1; lfs moves down one level

delete code common with FFS; add inode truncation code
checkpoint before integration

lint
