Yeah, looks everything is good after reverting the following two patches: Revert "io_uring/cmd: add iovec cache for commands" Revert "io_uring/cmd: introduce io_uring_cmd_import_fixed_vec" BTW I feel io_uring_cmd_import_fixed_vec is useful for using ublk zc to write stacking target, plain readv/writev works just fine without zc. thanks, Ming
