Subject: [PATCH v3] dm vdo: use get_random_u32() where appropriate
Date: Sun, 5 Apr 2026 16:47:13 +0100 [thread overview]
Message-ID: <20260405154713.4660-1-devnexen@gmail.com> (raw)
Use the typed random integer helpers instead of
get_random_bytes() when filling a single integer variable.
The helpers return the value directly, require no pointer
or size argument, and better express intent.
