Subject: [PATCH v2 1/5] Documentation/kcov: Include types.h in the example.
Date: Thu, 23 Sep 2021 18:47:37 +0200 [thread overview]
Message-ID: <20210923164741.1859522-2-bigeasy@linutronix.de> (raw)
In-Reply-To: <20210923164741.1859522-1-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.
