The most likely explanation is some slab # corruption, possibly triggered due to CONFIG_SLUB_DEBUG_ON. See [1]. # # It ends up having a few other problems too, like build errors on # arch/arc, and Geert reporting it using much more memory on m68k [3] (it # probably does so elsewhere too, but it is probably just more noticeable # on m68k). # # The architecture issues (both build and memory use) are likely just # because this change effectively force-enabled STACKDEPOT (along with a # very bad default value for the stackdepot hash size). But together with # the xfs issue, this all smells like "this commit was not ready" to me. # # Link: https://lore.kernel.org/linux-xfs/YPE3l82acwgI2OiV@infradead.org/ [1] # Link: https://lore.kernel.org/lkml/202107150600.LkGNb4Vb-lkp@intel.com/ [2] # Link: https://lore.kernel.org/lkml/CAMuHMdW=eoVzM1Re5FVoEN87nKfiLmM2+Ah7eNu2KXEhCvbZyA@mail.gmail.com/ [3] # Reported-by: Christoph Hellwig <hch@infradead.org> # Reported-by: kernel test robot <lkp@intel.com> # Reported-by: Geert Uytterhoeven <geert@linux-m68k.org> # Cc: Andrew Morton <akpm@linux-foundation.org> # Cc: Vlastimil Babka <vbabka@suse.cz> # Cc: Randy Dunlap <rdunlap@infradead.org> # Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/aarch64-linux/bin/aarch64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/aarch64-linux/bin/aarch64-linux-ld --version # < git log --format=%s --max-count=1 ae14c63a9f20d49dacfb6f3fa3fb11b3b4eb11bf # < make -s -j 24 ARCH=arm64 O=/kisskb/build/linus-rand_arm64-randconfig_arm64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/aarch64-linux/bin/aarch64-linux- randconfig # Added to kconfig CONFIG_PREVENT_FIRMWARE_BUILD=y # < make -s -j 24 ARCH=arm64 O=/kisskb/build/linus-rand_arm64-randconfig_arm64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/aarch64-linux/bin/aarch64-linux- help # make -s -j 24 ARCH=arm64 O=/kisskb/build/linus-rand_arm64-randconfig_arm64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/aarch64-linux/bin/aarch64-linux- olddefconfig # make -s -j 24 ARCH=arm64 O=/kisskb/build/linus-rand_arm64-randconfig_arm64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/aarch64-linux/bin/aarch64-linux- Completed OK # rm -rf /kisskb/build/linus-rand_arm64-randconfig_arm64-gcc8 # Build took: 0:06:31.898050
