CVS commit: [ad-namecache] src/sys

["Andrew Doran" <ad%netbsd.org@localhost>]

Module Name:    src
Committed By:   ad
Date:           Wed Jan  8 11:02:16 UTC 2020

Modified Files:
        src/sys/kern [ad-namecache]: init_sysctl.c vfs_cache.c vfs_vnode.c
        src/sys/sys [ad-namecache]: namei.src vnode_impl.h

Log Message:
Redo the namecache to focus on per-directory data structures, removing the
huge hashtable and nasty locking scheme.

Initially this uses rbtrees (because that's what's there).  The intent is
experiment with other data structures.
