The io_uring change is being overly # cautious with the save/restore/advance, but better safe than sorry and # we can always improve that and reduce the overhead if it proves to be # of concern. The only case to be worried about in this regard is huge # IO, where iteration can take a while to iterate segments. # # I spent some time writing test cases, and expanded the coverage quite # a bit from the last posting of this. liburing carries this regression # test case now: # # https://git.kernel.dk/cgit/liburing/tree/test/file-verify.c # # which exercises all of this. It now also supports provided buffers, # and explicitly tests for end-of-file/device truncation as well. # # On top of that, Pavel sanitized the IOPOLL retry path to follow the # exact same pattern as normal IO" # # * tag 'iov_iter.3-5.15-2021-09-17' of git://git.kernel.dk/linux-block: # io_uring: move iopoll reissue into regular IO path # Revert "iov_iter: track truncated size" # io_uring: use iov_iter state save/restore helpers # iov_iter: add helper to save iov_iter state # < /opt/cross/kisskb/br-mipsel-o32-full-2016.08-613-ge98b4dd/bin/mipsel-linux-gcc --version # < /opt/cross/kisskb/br-mipsel-o32-full-2016.08-613-ge98b4dd/bin/mipsel-linux-ld --version # < git log --format=%s --max-count=1 ddf21bd8ab984ccaa924f090fc7f515bb6d51414 # < make -s -j 48 ARCH=mips O=/kisskb/build/linus_mips-allmodconfig_mipsel CROSS_COMPILE=/opt/cross/kisskb/br-mipsel-o32-full-2016.08-613-ge98b4dd/bin/mipsel-linux- allmodconfig # Added to kconfig CONFIG_BUILD_DOCSRC=n # Added to kconfig CONFIG_MODULE_SIG=n # Added to kconfig CONFIG_SAMPLES=n # Added to kconfig CONFIG_MIPS_CPS_NS16550_BASE=0x1b0003f8 # Added to kconfig CONFIG_MIPS_CPS_NS16550_SHIFT=0 # Added to kconfig # < make -s -j 48 ARCH=mips O=/kisskb/build/linus_mips-allmodconfig_mipsel CROSS_COMPILE=/opt/cross/kisskb/br-mipsel-o32-full-2016.08-613-ge98b4dd/bin/mipsel-linux- help # make -s -j 48 ARCH=mips O=/kisskb/build/linus_mips-allmodconfig_mipsel CROSS_COMPILE=/opt/cross/kisskb/br-mipsel-o32-full-2016.08-613-ge98b4dd/bin/mipsel-linux- olddefconfig .config:13233:warning: override: reassigning to symbol MIPS_CPS_NS16550_SHIFT # make -s -j 48 ARCH=mips O=/kisskb/build/linus_mips-allmodconfig_mipsel CROSS_COMPILE=/opt/cross/kisskb/br-mipsel-o32-full-2016.08-613-ge98b4dd/bin/mipsel-linux- /kisskb/src/arch/mips/boot/dts/img/boston.dts:128.19-178.5: Warning (pci_device_reg): /pci@14000000/pci2_root@0,0,0: PCI unit address format error, expected "0,0" In file included from /opt/cross/kisskb/br-mipsel-o32-full-2016.08-613-ge98b4dd/bin/../lib/gcc/mipsel-buildroot-linux-uclibc/5.4.0/plugin/include/tm.h:35, from /opt/cross/kisskb/br-mipsel-o32-full-2016.08-613-ge98b4dd/bin/../lib/gcc/mipsel-buildroot-linux-uclibc/5.4.0/plugin/include/gcc-plugin.h:31, from /opt/cross/kisskb/br-mipsel-o32-full-2016.08-613-ge98b4dd/bin/../lib/gcc/mipsel-buildroot-linux-uclibc/5.4.0/plugin/include/plugin.h:23, from /kisskb/src/scripts/gcc-plugins/gcc-common.h:9, from /kisskb/src/scripts/gcc-plugins/latent_entropy_plugin.c:78: /opt/cross/kisskb/br-mipsel-o32-full-2016.08-613-ge98b4dd/bin/../lib/gcc/mipsel-buildroot-linux-uclibc/5.4.0/plugin/include/config/elfos.h:102:21: warning: invalid suffix on literal;
