It is enough to select KALLSYMS for this, KALLSYMS_ALL is not necessary. Moreover, Randy Dunlap reported that UBIFS causes the following Kconfig dependency warning: warning: (UBIFS_FS_DEBUG && LOCKDEP && LATENCYTOP) selects KALLSYMS_ALL which has unmet direct dependencies (DEBUG_KERNEL && KALLSYMS) The reason is that KALLSYMS_ALL requires DEBUG_KERNEL and KALLSYMS, so ideally, to select KALLSYMS_ALL we'd need to select DEBUG_KERNEL and KALLSYMS first. This seems to be too much to select. The easiest way to go is to forget about KALLSYMS_ALL and just select KALLSYMS when UBIFS debugging is enabled - that should be enough for stackdumps.
