Subject: [PATCH 2/2] mm/mprotect: drop 'sub' from batching context
Date: Tue, 23 Jun 2026 12:57:22 +0000 [thread overview]
Message-ID: <20260623125723.2503832-3-dev.jain@arm.com> (raw)
In-Reply-To: <20260623125723.2503832-1-dev.jain@arm.com>
Shorten the name of page_anon_exclusive_sub_batch by dropping the
"sub-batch" context - the function itself doesn't need this context.
Similarly, drop "sub" from sub_batch_idx, it is unnecessary and the
usage is clear enough.
