The quilt patch titled

has been removed from the -mm tree.  Its filename was
     mm-split-off-__bdi_set_max_ratio-function.patch

Subject: mm: split off __bdi_set_max_ratio() function
Date: Fri, 18 Nov 2022 16:52:01 -0800

This splits off __bdi_set_max_ratio() from bdi_set_max_ratio().
__bdi_set_max_ratio() will also be called from bdi_set_max_bytes(),
which will be introduced in the next patch.
