With the latter in place, we just need # buffered write async support and we're done relying on kthreads for # the fast path. In detail: # # - Cleanup how memory accounting is done on ring setup/free (Bijan) # # - sq array offset calculation fixup (Dmitry) # # - Consistently handle blocking off O_DIRECT submission path (me) # # - Support proper async buffered reads, instead of relying on kthread # offload for that. This uses the page waitqueue to drive retries # from task_work, like we handle poll based retry. (me) # # - IO completion optimizations (me) # # - Fix race with accounting and ring fd install (me) # # - Support EPOLLEXCLUSIVE (Jiufei) # # - Get rid of the io_kiocb unionizing, made possible by shrinking # other bits (Pavel) # # - Completion side cleanups (Pavel) # # - Cleanup REQ_F_ flags handling, and kill off many of them (Pavel) # # - Request environment grabbing cleanups (Pavel) # # - File and socket read/write cleanups (Pavel) # # - Improve kiocb_set_rw_flags() (Pavel) # # - Tons of fixes and cleanups (Pavel) # # - IORING_SQ_NEED_WAKEUP clear fix (Xiaoguang)" # # * tag 'for-5.9/io_uring-20200802' of git://git.kernel.dk/linux-block: (127 commits) # io_uring: flip if handling after io_setup_async_rw # fs: optimise kiocb_set_rw_flags() # io_uring: don't touch 'ctx' after installing file descriptor # io_uring: get rid of atomic FAA for cq_timeouts # io_uring: consolidate *_check_overflow accounting # io_uring: fix stalled deferred requests # io_uring: fix racy overflow count reporting # io_uring: deduplicate __io_complete_rw() # io_uring: de-unionise io_kiocb # io-wq: update hash bits # io_uring: fix missing io_queue_linked_timeout() # io_uring: mark ->work uninitialised after cleanup # io_uring: deduplicate io_grab_files() calls # io_uring: don't do opcode prep twice # io_uring: clear IORING_SQ_NEED_WAKEUP after executing task works # io_uring: batch put_task_struct() # tasks: add put_task_struct_many() # io_uring: return locked and pinned page accounting # io_uring: don't miscount pinned memory # io_uring: don't open-code recv kbuf managment # ... # < /opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 cdc8fcb49905c0b67e355e027cb462ee168ffaa3 # < make -s -j 48 ARCH=powerpc O=/kisskb/build/linus-rand_powerpc-randconfig_powerpc-gcc9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux- randconfig KCONFIG_SEED=0xADBB2030 # Added to kconfig CONFIG_STANDALONE=y # Added to kconfig CONFIG_BUILD_DOCSRC=n # Added to kconfig CONFIG_MODULE_SIG=n # Added to kconfig CONFIG_CPU_BIG_ENDIAN=y # Added to kconfig CONFIG_PPC64=y # Added to kconfig CONFIG_PPC_DISABLE_WERROR=y # Added to kconfig CONFIG_SECTION_MISMATCH_WARN_ONLY=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_LD_HEAD_STUB_CATCH=y # Added to kconfig CONFIG_TRIM_UNUSED_KSYMS=n # Added to kconfig CONFIG_UBSAN=n # < make -s -j 48 ARCH=powerpc O=/kisskb/build/linus-rand_powerpc-randconfig_powerpc-gcc9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux- help # make -s -j 48 ARCH=powerpc O=/kisskb/build/linus-rand_powerpc-randconfig_powerpc-gcc9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig .config:4682:warning: override: reassigning to symbol STANDALONE .config:4684:warning: override: reassigning to symbol MODULE_SIG .config:4685:warning: override: reassigning to symbol CPU_BIG_ENDIAN .config:4685:warning: override: CPU_BIG_ENDIAN changes choice state .config:4688:warning: override: reassigning to symbol SECTION_MISMATCH_WARN_ONLY .config:4689:warning: override: reassigning to symbol PREVENT_FIRMWARE_BUILD # make -s -j 48 ARCH=powerpc O=/kisskb/build/linus-rand_powerpc-randconfig_powerpc-gcc9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux- /kisskb/src/drivers/vfio/pci/vfio_pci_nvlink2.c: In function 'vfio_pci_nvgpu_release': /kisskb/src/drivers/vfio/pci/vfio_pci_nvlink2.c:101:10: error: implicit declaration of function 'mm_iommu_put'; did you mean 'mm_iommu_init'?
