[PATCH v2 08/19] hashmap_remove takes "const struct hashmap_entry *"

From
EWEric Wong <e@80x24.org>
Date
Sep 24, 2019, 01:03 UTC
Message-ID
<20190924010324.22619-9-e@80x24.org>
In-Reply-To
<20190924010324.22619-1-e@80x24.org>

This is less error-prone than "const void *" as the compiler now detects invalid types being passed.
