find should complain more clearly on backtrack failure and abort |

Hi,
I noticed a sort of failure mode while diagnosing an odd problem with our NFS
server. Specifically, it looks like find is using 'open("..")' to ascend the
directory tree, but this may fail, in which case find seems to emit a
"permission denied" and abort.
I think a normal user would assume that this error message just means that the
particular directory cannot be visited, but that things are otherwise fine. In
fact it appears that find completely gives up in this case, therefore not
searching the rest of the tree (even though it could in principle do so without
error). If this is so, it seems like the error message should state this
clearly. For example: "backtrack failed--find aborted!" or some such, to
indicate that the results of the run are fairly meaningless.
I didn't have time to look through the source at length, so it's possible that
I'm misunderstanding what's going on.
Regards,
Mike
