Given that the cache target was significantly reworked for 4.12 I see no reason to sit on these advances until 4.13 considering the favorable results associated with such minimalist tweaks. * tag 'for-4.12/dm-fixes-2' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm: dm cache: handle kmalloc failure allocating background_tracker struct dm bufio: make the parameter "retain_bytes" unsigned long dm mpath: multipath_clone_and_map must not return -EIO dm mpath: don't return -EIO from dm_report_EIO dm rq: add a missing break to map_request dm space map disk: fix some book keeping in the disk space map dm thin metadata: call precommit before saving the roots dm cache policy smq: don't do any writebacks unless IDLE dm cache: simplify the IDLE vs BUSY state calculation dm cache: track all IO to the cache rather than just the origin device's IO dm cache policy smq: stop preemptively demoting blocks dm cache policy smq: put newly promoted entries at the top of the multiqueue dm cache policy smq: be more aggressive about triggering a writeback dm cache policy smq: only demote entries in bottom half of the clean multiqueue dm cache: fix incorrect 'idle_time' reset in IO tracker # < /opt/cross/kisskb/gcc-4.6.3-nolibc/x86_64-linux/bin/x86_64-linux-gcc --version # < git log --format=%s --max-count=1 dac94e29110cd606dec37673644caf2cf6fd1dde # < make -j 10 ARCH=x86_64 O=/home/kisskb/slave/build/linus_x86_64-randconfig_x86_64 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/x86_64-linux/bin/x86_64-linux- randconfig KCONFIG_SEED=0x38FFCA14 warning: (KVM) selects TASKSTATS which has unmet direct dependencies (NET && MULTIUSER) # Added to kconfig CONFIG_STANDALONE=y # Added to kconfig CONFIG_PREVENT_FIRMWARE_BUILD=y # Added to kconfig CONFIG_CC_STACKPROTECTOR_STRONG=n # Added to kconfig CONFIG_GCC_PLUGINS=n # Added to kconfig CONFIG_GCC_PLUGIN_CYC_COMPLEXITY=n # Added to kconfig CONFIG_GCC_PLUGIN_SANCOV=n # Added to kconfig CONFIG_GCC_PLUGIN_LATENT_ENTROPY=n # yes \n | make -j 10 ARCH=x86_64 O=/home/kisskb/slave/build/linus_x86_64-randconfig_x86_64 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/x86_64-linux/bin/x86_64-linux- oldconfig yes: standard output: Broken pipe yes: write error # make -j 10 ARCH=x86_64 O=/home/kisskb/slave/build/linus_x86_64-randconfig_x86_64 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/x86_64-linux/bin/x86_64-linux- make[1]: Entering directory '/home/kisskb/slave/build/linus_x86_64-randconfig_x86_64' GEN ./Makefile scripts/kconfig/conf --silentoldconfig Kconfig warning: (KVM) selects TASKSTATS which has unmet direct dependencies (NET && MULTIUSER) warning: (KVM) selects TASKSTATS which has unmet direct dependencies (NET && MULTIUSER) scripts/Makefile.gcc-plugins:23: warning: cannot use CONFIG_KCOV: -fsanitize-coverage=trace-pc is not supported by compiler SYSTBL arch/x86/entry/syscalls/../../include/generated/asm/syscalls_32.h SYSHDR arch/x86/entry/syscalls/../../include/generated/asm/unistd_32_ia32.h SYSHDR arch/x86/entry/syscalls/../../include/generated/asm/unistd_64_x32.h SYSTBL arch/x86/entry/syscalls/../../include/generated/asm/syscalls_64.h HYPERCALLS arch/x86/entry/syscalls/../../include/generated/asm/xen-hypercalls.h SYSHDR arch/x86/entry/syscalls/../../include/generated/uapi/asm/unistd_32.h SYSHDR arch/x86/entry/syscalls/../../include/generated/uapi/asm/unistd_x32.h SYSHDR arch/x86/entry/syscalls/../../include/generated/uapi/asm/unistd_64.h HOSTCC scripts/basic/bin2c CHK include/config/kernel.release GEN ./Makefile WRAP arch/x86/include/generated/asm/clkdev.h WRAP arch/x86/include/generated/asm/dma-contiguous.h WRAP arch/x86/include/generated/asm/early_ioremap.h WRAP arch/x86/include/generated/asm/mcs_spinlock.h WRAP arch/x86/include/generated/asm/mm-arch-hooks.h UPD include/config/kernel.release CHK include/generated/uapi/linux/version.h UPD include/generated/uapi/linux/version.h gcc: error trying to exec 'cc1plus': execvp: No such file or directory Cannot use CONFIG_GCC_PLUGINS: your gcc installation does not support plugins, perhaps the necessary headers are missing? scripts/Makefile.gcc-plugins:63: recipe for target 'gcc-plugins-check' failed make[1]: *** [gcc-plugins-check] Error 1 make[1]: *** Waiting for unfinished jobs.... make[1]: *** wait: No child processes.
