From 823faa0f3edb93fac528bc35588cea81f0a77146 Mon Sep 17 00:00:00 2001 From: Jo-Philipp Wich Date: Sun, 5 Jan 2020 17:21:25 +0100 Subject: [PATCH] block: re-discover mtd devices on extroot mount retry When retrying extroot mounting after waiting for the underlying device to appear, the internal device cache was rebuilt without mtd devices, leading to the following error: block: extroot: unable to lookup root device /dev/... The extroot mount procedure needs access to the actual mtd root device to temporarily mount it for uuid file verification. Fix this error by rebuilding the cache with mtd devices to allow the `check_extroot()` procedure to find the internal root device.
