f2fs: merge flags in struct f2fs_sb_info
Currently, there are several variables with Boolean type as below: struct f2fs_sb_info { ... int s_dirty; bool need_fsck; bool s_closing; ... bool por_doing; ... } For this there are some issues: 1. there are some space of f2fs_sb_info is wasted due to aligning after Boolean type variables by compiler. 2. if we continuously add new flag into f2fs_sb_info, structure will be messed up. So in this patch, we try to: 1. switch s_dirty to Boolean type variable since it has two status 0/1. 2. merge s_dirty/need_fsck/s_closing/por_doing variables into s_flag. 3. introduce an enum type which can indicate different states of sbi. 4. use new introduced universal interfaces is_sbi_flag_set/{set,clear}_sbi_flag to operate flags for sbi. After that, above issues will be fixed. Signed-off-by: Chao Yu <chao2.yu@samsung.com> Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>
