From 5a72e899ceb465d731c413d57c6c12cdbf88303c Mon Sep 17 00:00:00 2001 From: Jens Axboe Date: Tue, 12 Oct 2021 09:24:29 -0600 Subject: block: add a struct io_comp_batch argument to fops->iopoll() struct io_comp_batch contains a list head and a completion handler, which will allow completions to more effciently completed batches of IO. For now, no functional changes in this patch, we just define the io_comp_batch structure and add the argument to the file_operations iopoll handler.
