Its filename was mm-add-bdi_set_min_bytes-function.patch This patch was dropped because it was merged into the mm-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: Stefan Roesch Subject: mm: add bdi_set_min_bytes() function Date: Fri, 18 Nov 2022 16:52:07 -0800 This introduces the bdi_set_min_bytes() function. The min_bytes function does not store the min_bytes value. Instead it converts the min_bytes value into the corresponding ratio value.
