Subject: [PATCH 2/2] include/bitmap.h: add new functions to documentation
Date: Wed, 4 Mar 2020 15:09:20 +0100 [thread overview]
Message-ID: <20200304140920.6109-3-wsa+renesas@sang-engineering.com> (raw)
In-Reply-To: <20200304140920.6109-1-wsa+renesas@sang-engineering.com>
I found these functions only by chance although I was looking exactly
for something like them. So, add them to the list of functions to make
them more visible.
Fixes: e837dfde15a4 ("bitmap: genericize percpu bitmap region iterators")
