From 48d15436fde6feebcded7bd0fdc8ea4a9181b8fa Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Tue, 26 Jan 2021 15:52:47 +0100 Subject: mm: remove get_swap_bio Just reuse the block_device and sector from the swap_info structure, just as used by the SWP_SYNCHRONOUS path. Also remove the checks for NULL returns from bio_alloc as that can't happen for sleeping allocations.
