Subject: [PATCH] Fix single arg wildcard listings
The docs say we can do stuff like
# bpftrace -l "*sleep*"
so we should probably implement it. We probably regressed on this during
the probe matching refactoring.

Subject: [PATCH] Update bio* tools to work on RHEL9
Kernel commit:
9e6c144e5fee block: inline hot paths of blk_account_io_*()
renamed some functions used in the tools.
Kernel commit:
5f8d3bf600d2 block: move struct request to blk-mq.h
moved "struct request" to a different header.
This fixes both issues.
