(lib/Kconfig.debug:) config DEBUG_FS bool "Debug Filesystem" depends on SYSFS I ask because kconfig now (in linux-next) warns about kconfig dependency problems, like this one: warning: (TREE_RCU_TRACE || AMD_IOMMU_STATS && AMD_IOMMU || MTD_UBI_DEBUG && MTD && SYSFS && MTD_UBI || UBIFS_FS_DEBUG && MISC_FILESYSTEMS && UBIFS_FS || DEBUG_KMEMLEAK && DEBUG_KERNEL && EXPERIMENTAL && !MEMORY_HOTPLUG && (X86 || ARM || PPC || S390 || SPARC64 || SUPERH || MICROBLAZE) && SYSFS || TRACING || X86_PTDUMP && DEBUG_KERNEL || BLK_DEV_IO_TRACE && TRACING_SUPPORT && FTRACE && SYSFS && BLOCK) selects DEBUG_FS which has unmet direct dependencies (SYSFS) because TREE_RCU_TRACE selects DEBUG_FS, even when SYSFS is not enabled. I first made a patch to have TREE_RCU_TRACE depend on SYSFS, but then I just removed the DEBUG_FS "depends on SYSFS" and the kernel builds fine, hence the first question. thanks, --- ~Randy *** Remember to use Documentation/SubmitChecklist when testing your code *** -- To unsubscribe from this list: send the line "unsubscribe linux-next" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
