Since we have moved all other profiles handling into their own functions, now the main body of scrub_stripe() is just handling RAID56 profiles. There is no need to address other profiles in the main loop of scrub_stripe(), so we can remove those dead branches. Since we're here, also slightly change the timing of initialization of variables like @offset, @increment and @logical. Especially for @logical, we don't really need to initialize it for btrfs_extent_root()/btrfs_csum_root(), we can use bg->start for that purpose. Now those variables are only initialize for RAID56 branches. Signed-off-by: NQu Wenruo <wqu@suse.com> Signed-off-by: NDavid Sterba <dsterba@suse.com>
