Subject: [RFC PATCH 14/20] mm: Allocate kcompactd on its node
Date: Fri, 26 Jul 2024 23:56:50 +0200	[thread overview]
Message-ID: <20240726215701.19459-15-frederic@kernel.org> (raw)
In-Reply-To: <20240726215701.19459-1-frederic@kernel.org>

kcompactd runs preferrably on a specific node. Allocate its task
structure accordingly for better memory locality.
