Subject[PATCH 4.4 72/97] perf tests kmod-path: Dont fail if compressed modules arent supported
Date
4.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Kim Phillips <kim.phillips@arm.com>


[ Upstream commit 805b151a1afd24414706a7f6ae275fbb9649be74 ]

__kmod_path__parse() uses is_supported_compression() to determine and
parse out compressed module file extensions. On systems without zlib,
this test fails and __kmod_path__parse() continues to strcmp "ko" with
"gz". Don't do this on those systems.
