Recall that this was added after the device-dax subsystem # moved from /sys/class/dax to /sys/bus/dax for its sysfs organization. # All recent functionality depends on /sys/bus/dax. # # Some other miscellaneous cleanups and reflink prep patches are # included as well. # # Summary: # # - Simplify the dax_operations API: # # - Eliminate bdev_dax_pgoff() in favor of the filesystem # maintaining and applying a partition offset to all its DAX iomap # operations. # # - Remove wrappers and device-mapper stacked callbacks for # ->copy_from_iter() and ->copy_to_iter() in favor of moving # block_device relative offset responsibility to the # dax_direct_access() caller. # # - Remove the need for an @bdev in filesystem-DAX infrastructure # # - Remove unused uio helpers copy_from_iter_flushcache() and # copy_mc_to_iter() as only the non-check_copy_size() versions are # used for DAX. # # - Prepare XFS for the pending (next merge window) DAX+reflink support # # - Remove deprecated DEV_DAX_PMEM_COMPAT support # # - Cleanup a straggling misuse of the GUID api" # # * tag 'libnvdimm-for-5.17' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm: (38 commits) # iomap: Fix error handling in iomap_zero_iter() # ACPI: NFIT: Import GUID before use # dax: remove the copy_from_iter and copy_to_iter methods # dax: remove the DAXDEV_F_SYNC flag # dax: simplify dax_synchronous and set_dax_synchronous # uio: remove copy_from_iter_flushcache() and copy_mc_to_iter() # iomap: turn the byte variable in iomap_zero_iter into a ssize_t # memremap: remove support for external pgmap refcounts # fsdax: don't require CONFIG_BLOCK # iomap: build the block based code conditionally # dax: fix up some of the block device related ifdefs # fsdax: shift partition offset handling into the file systems # dax: return the partition offset from fs_dax_get_by_bdev # iomap: add a IOMAP_DAX flag # xfs: pass the mapping flags to xfs_bmbt_to_iomap # xfs: use xfs_direct_write_iomap_ops for DAX zeroing # xfs: move dax device handling into xfs_{alloc,free}_buftarg # ext4: cleanup the dax handling in ext4_fill_super # ext2: cleanup the dax handling in ext2_fill_super # fsdax: decouple zeroing from the iomap buffered I/O code # ... # < /opt/cross/kisskb/korg/gcc-11.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-11.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 3acbdbf42e943d85174401357a6b6243479d4c76 # < make -s -j 8 ARCH=powerpc O=/kisskb/build/linus-rand_powerpc-randconfig_powerpc-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux- randconfig # 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 8 ARCH=powerpc O=/kisskb/build/linus-rand_powerpc-randconfig_powerpc-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux- help # make -s -j 8 ARCH=powerpc O=/kisskb/build/linus-rand_powerpc-randconfig_powerpc-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig .config:4753:warning: override: reassigning to symbol PPC64 .config:4754:warning: override: reassigning to symbol PPC_DISABLE_WERROR .config:4756:warning: override: reassigning to symbol PREVENT_FIRMWARE_BUILD .config:4758:warning: override: reassigning to symbol GCC_PLUGINS .config:4761:warning: override: reassigning to symbol UBSAN # make -s -j 8 ARCH=powerpc O=/kisskb/build/linus-rand_powerpc-randconfig_powerpc-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux- /kisskb/src/arch/powerpc/tools/relocs_check.sh: 60: echo: echo: I/O error Completed OK # rm -rf /kisskb/build/linus-rand_powerpc-randconfig_powerpc-gcc11 # Build took: 0:09:00.676483
