[DTrace-devel] [PATCH 7/7] modules: support .gz and .xz-compressed modules

[Nick Alcock]

The module path ends in .ko.*:, where * depends on the compression
algorithm: so systems with compressed modules would skip all modules on
the incorrect grounds that none existed.

Add a few compression algorithms to make this subsystem work again.
(It is mostly invisible for in-tree modules.)
