Subject: [PATCH] arm64: Remove the check for CONFIG_TINY_RCU
Date: Sat, 14 Sep 2024 18:00:40 +0900 [thread overview]
Message-ID: <20240914090040.166671-1-ryotkkr98@gmail.com> (raw)
Since the commit 4b3dc9679cf77 ("arm64: force CONFIG_SMP=y and remove
redundant #ifdefs"), arm64 defaults to CONFIG_SMP but TINY_RCU is cofigured
only for !SMP systems.
Remove the check for CONFIG_TINY_RCU as it should always be false.
