Subject: kernel: allow rootfs splitters to work without CONFIG_MTD_ROOTFS_SPLIT
X-Git-Url: https://git.archive.openwrt.org/?a=commitdiff_plain;h=b91c599987ef34012e058e1eca9dc60d11c136c9;p=openwrt.git

kernel: allow rootfs splitters to work without CONFIG_MTD_ROOTFS_SPLIT

We want to remove that old (built-in) splitter at some point.
