Filipe Manana 2e0cdaa028 btrfs: remove unnecessary extent map initializations ... When allocating an extent map, we use kmem_cache_zalloc() which guarantees the returned memory is initialized to zeroes, therefore it's pointless to initialize the generation and flags of the extent map to zero again. Remove those initializations, as they are pointless and slightly increase the object text size. Before removing them: $ size fs/btrfs/extent_map.o text data bss dec hex filename 9241 274 24 9539 2543 fs/btrfs/extent_map.o After removing them: $ size fs/btrfs/extent_map.o text data bss dec hex filename 9209 274 24 9507 2523 fs/btrfs/extent_map.o Signed-off-by: Filipe Manana <fdmanana@suse.com> Reviewed-by: David Sterba <dsterba@suse.com> Signed-off-by: David Sterba <dsterba@suse.com>		2022-09-29 17:08:30 +02:00
