The first patch is preparation with no functional changes, makes do_mkdirat accept struct filename pointer rather than the user string. The second one leverages that to implement mkdirat in io_uring. Based on for-5.11/io_uring. Changes since v1: - do not mess with struct filename's refcount in do_mkdirat, instead add and use __filename_create() that does not drop the name on success; Dmitry Kadashev (2): fs: make do_mkdirat() take struct filename io_uring: add support for IORING_OP_MKDIRAT fs/internal.h | 1 + fs/io_uring.c | 58 +++++++++++++++++++++++++++++++++++ fs/namei.c | 25 +++++++++++---- include/uapi/linux/io_uring.h | 1 + 4 files changed, 79 insertions(+), 6 deletions(-)
