parentbtrfs: Introduce btrfs_io_geometry infrastructure (diff)
btrfs: Use btrfs_get_io_geometry appropriately
Presently btrfs_map_block is used not only to do everything necessary to map a bio to the underlying allocation profile but it's also used to identify how much data could be written based on btrfs' stripe logic without actually submitting anything. This is achieved by passing NULL for 'bbio_ret' parameter. This patch refactors all callers that require just the mapping length by switching them to using btrfs_io_geometry instead of calling btrfs_map_block with a special NULL value for 'bbio_ret'. No functional change. Signed-off-by: Nikolay Borisov <nborisov@suse.com> Reviewed-by: David Sterba <dsterba@suse.com> Signed-off-by: David Sterba <dsterba@suse.com>
