From 793e560a6b7ca99c3dedc1b717645d07fa5cff8e Mon Sep 17 00:00:00 2001 From: Bernd Schubert Date: Tue, 3 Dec 2024 11:31:05 +0100 Subject: io_uring: Change res2 parameter type in io_uring_cmd_done commit a07d2d7930c75e6bf88683b376d09ab1f3fed2aa upstream. Change the type of the res2 parameter in io_uring_cmd_done from ssize_t to u64. This aligns the parameter type with io_req_set_cqe32_extra, which expects u64 arguments. The change eliminates potential issues on 32-bit architectures where ssize_t might be 32-bit. Only user of passing res2 is drivers/nvme/host/ioctl.c and it actually passes u64.
