eliminate extraneous include of conf.h

don't try to truncate inodes on read-only file systems (from sun!shannon)

must zero out unused portion of partial blocks when truncating files

Change to includes. no more ../h

increase size of hash table header to reduce collisions

use new `cacheinval' macro

iget must lock old inode before dqrele()

save time, use ILOCK and IUNLOCK to avoid call overhead

eliminate unnecessary panic when id's wrap

convert namei cache to hold soft references to inodes so that
. and .. may be placed in the cache

remove paranoid test; make hashsize a power of two (avoid unsigned
modulo)

use ITIME in irele to update times in irele without write to disk

force iupdate from irele if count still > 0,
avoiding delayed updates from namei cache

4.2 distribution

update inode time stamps when no work so touch works

indirtrunc always returns blocks released for use with i_blocks;
macro-ized to eliminate DEV_BSHIFT

botched non-QUOTA code (from kre)

guard against negative mod parameters

rewrite itrunc and indirtrunc to work (and handle triple indirect
blocks as well)

merge of 4.1b and 4.1c

missing declaration of size
