Hi, i am trying to develop a blk driver, i have registered my I/O handler function with blk_init_queue(my function, lock)
my function get called for every Read and write as expected but all I/O are page sized only. so even if i send 32K I/O from application to my device, it gets me 8 4k(page size ) I/O. so i have now two choice: 1. either i get I/O before got split 2. after elevator has aggregated them. i have tried QUEUE_FLAG_PLUGGED to get large I/O but I/O are not consistent(corruption happens after read and writing with QUEUE_FLAG_PLUGGED). any info would be highly appreciated. thanks -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
