That will then always trigger the # "start >= extent_end" test, which will end up never falling through to # the use of that variable. # # But the code is certainly not obvious, and the compiler warning looks # reasonable. Make 'extent_type' an int, and initialize it to an invalid # negative value, which seems to be the common pattern in other places. # # Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> # < /opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux-gcc --version # < /opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux-ld --version # < git log --format=%s --max-count=1 7e74e235bb31a1fefc28d5303da0718b88627ea8 # < make -s -j 48 ARCH=arm64 O=/kisskb/build/linus-rand_arm64-randconfig_arm64-gcc5.4 CROSS_COMPILE=/opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux- randconfig KCONFIG_SEED=0x7AFA4B56 # Added to kconfig CONFIG_PREVENT_FIRMWARE_BUILD=y # yes \n | make -s -j 48 ARCH=arm64 O=/kisskb/build/linus-rand_arm64-randconfig_arm64-gcc5.4 CROSS_COMPILE=/opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux- oldconfig yes: standard output: Broken pipe # make -s -j 48 ARCH=arm64 O=/kisskb/build/linus-rand_arm64-randconfig_arm64-gcc5.4 CROSS_COMPILE=/opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux- arch/arm64/Makefile:27: ld does not support --fix-cortex-a53-843419; kernel may be susceptible to erratum arch/arm64/Makefile:40: LSE atomics not supported by binutils arch/arm64/Makefile:27: ld does not support --fix-cortex-a53-843419; kernel may be susceptible to erratum arch/arm64/Makefile:40: LSE atomics not supported by binutils Completed OK # rm -rf /kisskb/build/linus-rand_arm64-randconfig_arm64-gcc5.4 # Build took: 0:04:43.104749
