From 265fdfa6ce0a79df3b880bbf39d9a00a0435687f Mon Sep 17 00:00:00 2001 From: David Sterba Date: Wed, 1 Jul 2020 21:19:09 +0200 Subject: btrfs: replace s_blocksize_bits with fs_info::sectorsize_bits The value of super_block::s_blocksize_bits is the same as fs_info::sectorsize_bits, but we don't need to do the extra dereferences in many functions and storing the bits as u32 (in fs_info) generates shorter assembly.
