From be297968da22cf40c9c419df51e71ba8856a2ec2 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Tue, 1 Nov 2016 07:40:16 -0600 Subject: mm: only include blk_types in swap.h if CONFIG_SWAP is enabled It's only needed for the CONFIG_SWAP-only use of bio_end_io_t. Because CONFIG_SWAP implies CONFIG_BLOCK this will allow to drop some ifdefs in blk_types.h. Instead we'll need to add a few explicit includes that were implicit before, though.
