CVS commit: [ad-namecache] src/sys/kern

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

Module Name:    src
Committed By:   ad
Date:           Sun Mar 22 01:58:22 UTC 2020

Modified Files:
        src/sys/kern [ad-namecache]: vfs_cache.c

Log Message:
- rb_tree_insert_node() refuses to insert duplicate nodes.  It always
  returns a pointer to the current node in the tree for the given key.
  Therefore the call to rb_tree_lookup_node() in cache_enter() is not
  needed.

- Adjust a comment and move some code for clarity.
