But if there is a bufio cache # miss, or an error, then the tasklet will fallback to using workqueue. # # - Incremental changes to both dm-bufio and the DM verity target to use # jump_label to minimize cost of branching associated with the niche # "try_verify_in_tasklet" feature. DM-bufio in particular is used by # quite a few other DM targets so it doesn't make sense to incur # additional bufio cost in those targets purely for the benefit of this # niche verity feature if the feature isn't ever used. # # - Optimize verity_verify_io, which is used by both workqueue and # tasklet based verification, if FEC is not configured or tasklet based # verification isn't used. # # - Remove DM verity target's verify_wq's use of the WQ_CPU_INTENSIVE # flag since it uses WQ_UNBOUND. Also, use the WQ_HIGHPRI flag if # "try_verify_in_tasklet" is specified. # # * tag 'for-6.0/dm-changes-2' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm: # dm verity: have verify_wq use WQ_HIGHPRI if "try_verify_in_tasklet" # dm verity: remove WQ_CPU_INTENSIVE flag since using WQ_UNBOUND # dm verity: only copy bvec_iter in verity_verify_io if in_tasklet # dm verity: optimize verity_verify_io if FEC not configured # dm verity: conditionally enable branching for "try_verify_in_tasklet" # dm bufio: conditionally enable branching for DM_BUFIO_CLIENT_NO_SLEEP # dm verity: allow optional args to alter primary args handling # dm verity: Add optional "try_verify_in_tasklet" feature # dm bufio: Add DM_BUFIO_CLIENT_NO_SLEEP flag # dm bufio: Add flags argument to dm_bufio_client_create # < /opt/cross/kisskb/korg/gcc-11.1.0-nolibc/x86_64-linux/bin/x86_64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-11.1.0-nolibc/x86_64-linux/bin/x86_64-linux-ld --version # < git log --format=%s --max-count=1 20cf903a0c407cef19300e5c85a03c82593bde36 # < make -s -j 120 ARCH=x86_64 O=/kisskb/build/linus-rand_x86_64-randconfig_x86_64-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/x86_64-linux/bin/x86_64-linux- randconfig # 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 # Added to kconfig CONFIG_BPF_PRELOAD=n # Added to kconfig # < make -s -j 120 ARCH=x86_64 O=/kisskb/build/linus-rand_x86_64-randconfig_x86_64-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/x86_64-linux/bin/x86_64-linux- help # make -s -j 120 ARCH=x86_64 O=/kisskb/build/linus-rand_x86_64-randconfig_x86_64-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/x86_64-linux/bin/x86_64-linux- olddefconfig .config:5695:warning: override: reassigning to symbol STANDALONE .config:5696:warning: override: reassigning to symbol PREVENT_FIRMWARE_BUILD .config:5698:warning: override: reassigning to symbol GCC_PLUGINS # make -s -j 120 ARCH=x86_64 O=/kisskb/build/linus-rand_x86_64-randconfig_x86_64-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/x86_64-linux/bin/x86_64-linux- vmlinux.o: warning: objtool: __svm_vcpu_run+0xb8: BP used as a scratch register vmlinux.o: warning: objtool: __svm_sev_es_vcpu_run+0x20: BP used as a scratch register BTF: .tmp_vmlinux.btf: pahole version v1.12 is too old, need at least v1.16 Failed to generate BTF for vmlinux Try to disable CONFIG_DEBUG_INFO_BTF make[1]: *** [/kisskb/src/Makefile:1165: vmlinux] Error 1 make: *** [Makefile:219: __sub-make] Error 2 Command 'make -s -j 120 ARCH=x86_64 O=/kisskb/build/linus-rand_x86_64-randconfig_x86_64-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/x86_64-linux/bin/x86_64-linux- ' returned non-zero exit status 2 # rm -rf /kisskb/build/linus-rand_x86_64-randconfig_x86_64-gcc11 # Build took: 0:02:32.042005
