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/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 ddf21bd8ab984ccaa924f090fc7f515bb6d51414 # < make -s -j 120 ARCH=powerpc O=/kisskb/build/linus_ppc64_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- ppc64_defconfig # < make -s -j 120 ARCH=powerpc O=/kisskb/build/linus_ppc64_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- help # make -s -j 120 ARCH=powerpc O=/kisskb/build/linus_ppc64_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig # make -s -j 120 ARCH=powerpc O=/kisskb/build/linus_ppc64_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- Completed OK # rm -rf /kisskb/build/linus_ppc64_defconfig_powerpc-gcc5 # Build took: 0:02:19.987826
