Comment 74 for bug 506798

No, sorry, no way to determine what the ino is for the new file system
without talking to the server.

Doing an ls in a directory full of many autofs mounted file systems
should not trigger mounts for all of those file systems. This will
cause a bigger performance problem than the original perceived
problem ever did.

Perhaps the right way to address this is to flag the returned
directory entries to the user level with something which indicates
that the metadata information for that entry will change if the
file system which would be mounted there was actually mounted
there. This would eliminate most of the extra stat calls that Jim
Meyering is worried about.
