From a702a692cd7559053ea573f4e2c84828f0e62824 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Fri, 24 Jan 2020 01:01:27 +0800 Subject: bcache: use a separate data structure for the on-disk super block Split out an on-disk version struct cache_sb with the proper endianness annotations. This fixes a fair chunk of sparse warnings, but there are some left due to the way the checksum is defined.
