Another day, another spin. This is v14, and it fixes a few silly issues with fsync, mainly, but also various little fixes and tweaks all over the map. The liburing git repo has a full set of man pages for this, though they could probably still use a bit of polish. I'd also like to see a io_uring(7) man page to describe the overall design of the project, expect that in the not-so-distant future. You can clone that here: git://git.kernel.dk/liburing Patches are against 5.0-rc5, and can also be found in my io_uring branch here: git://git.kernel.dk/linux-block io_uring Changes since v13: - Use READ/WRITE_ONCE anywhere we touch the shared data - Cache if we need to account/unaccount memory - Fix fsync file grabbing - Fix oops with fsync and deferred async list - Fix final fput() of fixed files AFTER adding to socket - Use correct iterator to free fixed user bufs - up/down_read() for mmap_sem when mapping buffers - completion -> complete in Kconfig help entry - Ensure malicious app can't trick NOP into leaking a file - Add a few comments, address a few review comments Documentation/filesystems/vfs.txt | 3 + arch/x86/entry/syscalls/syscall_32.tbl | 3 + arch/x86/entry/syscalls/syscall_64.tbl | 3 + block/bio.c | 59 +- fs/Makefile | 1 + fs/block_dev.c | 19 +- fs/file.c | 15 +- fs/file_table.c | 9 +- fs/gfs2/file.c | 2 + fs/io_uring.c | 2853 ++++++++++++++++++++++++ fs/iomap.c | 48 +- fs/xfs/xfs_file.c | 1 + include/linux/bio.h | 14 + include/linux/blk_types.h | 1 + include/linux/file.h | 2 + include/linux/fs.h | 15 +- include/linux/iomap.h | 1 + include/linux/sched/user.h | 2 +- include/linux/syscalls.h | 8 + include/net/af_unix.h | 1 + include/uapi/asm-generic/unistd.h | 8 +- include/uapi/linux/io_uring.h | 142 ++ init/Kconfig | 9 + kernel/sys_ni.c | 3 + net/Makefile | 2 +- net/unix/Kconfig | 5 + net/unix/Makefile | 2 + net/unix/af_unix.c | 63 +- net/unix/garbage.c | 68 +- net/unix/scm.c | 151 ++ net/unix/scm.h | 10 + 31 files changed, 3354 insertions(+), 169 deletions(-) -- Jens Axboe
