Hi,

Here are patches to fix bugs in fprobe.

The previous version is here.

https://lore.kernel.org/all/177555745233.1441308.6535024692186959381.stgit@mhiramat.tok.corp.google.com/

In this version, I added another bug in module callback
which calls kcalloc() in rcu_read_lock() section[1/2] which
is reported by Sashiko[1].

Thank you!
