Subject: [PATCH 1/5] Documentation/kcov: Include types.h in the example.
Date: Mon, 30 Aug 2021 19:26:23 +0200	[thread overview]
Message-ID: <20210830172627.267989-2-bigeasy@linutronix.de> (raw)
In-Reply-To: <20210830172627.267989-1-bigeasy@linutronix.de>

The first example code has includes at the top, the following two
example share that part. The last example (remote coverage collection)
requires the linux/types.h header file due its __aligned_u64 usage.

Add the linux/types.h to the top most example and a comment that the
header files from above are required as it is done in the second
example.
