Re-tested on arm64, amd64 and i386, this time everything seems fine so far. As I'm too lazy to have a separate test setup for the zlib level patch, I'm using a dummy implementation: --- a/fs/btrfs/zstd.c +++ b/fs/btrfs/zstd.c @@ -423,10 +423,16 @@ static int zstd_decompress(struct list_head *ws, unsigned char *data_in, return ret; } +static void zstd_set_level(struct list_head *ws, unsigned int type) +{ + // TODO +} + const struct btrfs_compress_op btrfs_zstd_compress = { .alloc_workspace = zstd_alloc_workspace, .free_workspace = zstd_free_workspace, .compress_pages = zstd_compress_pages, .decompress_bio = zstd_decompress_bio, .decompress = zstd_decompress, + .set_level = zstd_set_level, }; It might be worthwhile to do some early testing using different levels, though. 喵! -- ⢀⣴⠾⠻⢶⣦⠀ ⣾⠁⢠⠒⠀⣿⡁ A dumb species has no way to open a tuna can. ⢿⡄⠘⠷⠚⠋⠀ A smart species invents a can opener. ⠈⠳⣄⠀⠀⠀⠀ A master species delegates. -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
