CVS commit: src/usr.sbin/puffs/mount_psshfs

[Antti Kantee <pooka%netbsd.org@localhost>]

Module Name:    src
Committed By:   pooka
Date:           Fri Feb  9 23:36:17 UTC 2007

Modified Files:
        src/usr.sbin/puffs/mount_psshfs: node.c psshfs.c psshfs.h subr.c

Log Message:
Implement "superreaddir".  This issues a getattr for all the
directory entries already in readdir and caches the results instead
of waiting for each individial getattr from the kernel.  For
high-latency links the difference in "ls -l" is quite astounding
and even on my lan "ls -lR" is faster than for nfs in a normal
directory hierarchy (i.e. not one artifically setup to have thousands
of files per directory).

TODO: implement some sort of bandwidth/latency measurement in the
code and enable or disable this option based on than information
(and a command-line flag).
