[PATCH AUTOSEL for 4.4 077/101] perf tests kmod-path: Don't fail if compressed modules aren't supported

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Kim Phillips <kim.phillips@xxxxxxx>

[ 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.
