Hi, What is the maximum size of the data that can be read/written in a single bio ? I could locate two possible locations where I can calculate that : 1. #define BIO_MAX_PAGES 256 #define BIO_MAX_SIZE (BIO_MAX_PAGES << PAGE_CACHE_SHIFT) #define BIO_MAX_SECTORS (BIO_MAX_SIZE >> 9) Max = 1048576 2. #define UIO_MAXIOV 1024 Max = 4194304 Is there any other way that the bio could have been created that is reading/writing data in a larger size than any of the above ?
