Changes since v2: - revert the switch of the access process vm sysclls to iov_iter - refactor the import_iovec internals differently - switch aio to use __import_iovec Changes since v1: - improve a commit message - drop a pointless unlikely - drop the PF_FORCE_COMPAT flag - add a few more cleanups (including two from David Laight) Diffstat: arch/arm64/include/asm/unistd32.h | 10=20 arch/mips/kernel/syscalls/syscall_n32.tbl | 10=20 arch/mips/kernel/syscalls/syscall_o32.tbl | 10=20 arch/parisc/kernel/syscalls/syscall.tbl | 10=20 arch/powerpc/kernel/syscalls/syscall.tbl | 10=20 arch/s390/kernel/syscalls/syscall.tbl | 10=20 arch/sparc/kernel/syscalls/syscall.tbl | 10=20 arch/x86/entry/syscall_x32.c | 5=20 arch/x86/entry/syscalls/syscall_32.tbl | 10=20 arch/x86/entry/syscalls/syscall_64.tbl | 10=20 block/scsi_ioctl.c | 12=20 drivers/scsi/sg.c | 9=20 fs/aio.c | 38 -- fs/io_uring.c | 20 - fs/read_write.c | 362 +-------------= ------- fs/splice.c | 57 --- include/linux/compat.h | 24 - include/linux/fs.h | 11=20 include/linux/uio.h | 10=20 include/uapi/asm-generic/unistd.h | 12=20 lib/iov_iter.c | 161 +++++++-- mm/process_vm_access.c | 85 ---- net/compat.c | 4=20 security/keys/compat.c | 37 -- security/keys/internal.h | 5=20 security/keys/keyctl.c | 2=20 tools/include/uapi/asm-generic/unistd.h | 12=20 tools/perf/arch/powerpc/entry/syscalls/syscall.tbl | 10=20 tools/perf/arch/s390/entry/syscalls/syscall.tbl | 10=20 tools/perf/arch/x86/entry/syscalls/syscall_64.tbl | 10=20 30 files changed, 280 insertions(+), 706 deletions(-)
