Subject: [PATCH] simplify container_of_const()
Date: Fri, 19 Jul 2024 22:19:37 +0300 [thread overview]
Message-ID: <a088c95b-53d2-42ea-9eb3-ae81fbd07c1b@p183> (raw)
* add necessary parenthesis so that
container_of_const((expr1, expr2), T, member)
compiles without warnings,
* delete unnecessary parenthesis,
* delete unnecessary cast:
container_of(ptr, T, member)
has type "T*" and doesn't need any more casts.
