davidg 95/04/03 19:01:14 Modified: sys/kern kern_subr.c vfs_cache.c Log: kern_subr.c: Added a new type to uiomove - "UIO_NOCOPY" which causes it to update pointers and counts, but doesn't do any data copying. This is needed for upcoming changes to the way that the vnode pager does its page outs. Added a new hash init function call "phashinit" that allocates and initializes a prime number sized hash table. vfs_cache.c: Changed hashing algorithm to use the remainder of dividing by a prime number to improve the distribution characteristcs. Uses new phashinit function in kern_subr.c.
