Subject: [PATCH RFC rcu 01/19] srcu: Add whitespace to __SRCU_STRUCT_INIT() & __DEFINE_SRCU()
Date: Thu, 23 Mar 2023 17:19:20 -0700 [thread overview]
Message-ID: <20230324001938.3443499-1-paulmck@kernel.org> (raw)
In-Reply-To: <3db82572-f156-4a5d-b711-841aa28bd996@paulmck-laptop>
This is a whitespace-only commit with no change in functionality.
Its purpose is to prepare for later commits that: (1) Cause statically
allocated srcu_struct structures to rely on compile-time initialization
and (2) Move fields from the srcu_struct structure to a new srcu_usage
structure.
