Subject: [PATCH 06/13] perf tools: Add compression id into struct kmod_path
Date: Fri, 17 Aug 2018 11:48:06 +0200	[thread overview]
Message-ID: <20180817094813.15086-7-jolsa@kernel.org> (raw)
In-Reply-To: <20180817094813.15086-1-jolsa@kernel.org>

Storing decompression ID in the struct kmod_path, so it
can be later stored in the struct dso.

Switching the struct kmod_path::comp from bool to int
to return the compressions array index. Adding 0 index
item into compressions array, so the comp usage stays
as it was: 0 - no compression, != 0 index of compression.

Updating the kmod_path tests.
