RDMA/mlx5: reduce stack usage in mlx5_ib_ufile_hw_cleanup
This function has an array of eight mlx5_async_cmd structures, which often fits on the stack, but depending on the configuration can end up blowing the stack frame warning limit: drivers/infiniband/hw/mlx5/devx.c:2670:6: error: stack frame size (1392) exceeds limit (1280) in 'mlx5_ib_ufile_hw_cleanup' [-Werror,-Wframe-larger-than] Change this to a dynamic allocation instead. While a kmalloc() can theoretically fail, a GFP_KERNEL allocation under a page will block until memory has been freed up, so in the worst case, this only adds extra time in an already constrained environment.
