From e86dfd0a44b8dece1bee04f34762888ce92732a4 Mon Sep 17 00:00:00 2001 From: Ansuel Smith Date: Sun, 16 Jan 2022 03:54:58 +0100 Subject: [PATCH] ipq806x: rework rootfs conflicts patch for smem Now that smem actually free the leaked parts, when a rootfs partition is detected, the kernel panics as it try to free the static space allocated for the "ubi" name. Change the logic and fix the name at the allocate_partition function to correctly free the space allocated by smem.
