Subject: [RFC PATCH v3 11/14] mm: split off __bdi_set_min_ratio() function
Date: Mon, 24 Oct 2022 12:06:00 -0700	[thread overview]
Message-ID: <20221024190603.3987969-12-shr@devkernel.io> (raw)
In-Reply-To: <20221024190603.3987969-1-shr@devkernel.io>

This splits off the __bdi_set_min_ratio() function from the
bdi_set_min_ratio() function. The __bdi_set_min_ratio() function will
also be called from the bdi_set_min_bytes() function, which will be
introduced in the next patch.
