Hi,
Here are patches to fix bugs in fprobe.
The previous version is here.
https://lore.kernel.org/all/177573094819.3666478.11900825120958856397.stgit@xxxxxxxxxxxxxxxxxxxxxxxxxxxx/
In this version, I added another bugfix for registration
failure of fprobe [1/3] (since this is the patch for oldest bug),
and move retry-loop inside rhltable_walk_enter()/exit()[2/3].
Both are reported by Sashiko[1].

Thank you!
