Hi, In the implementation of file systems for 2.6 kernels, generic_file_read is often replaced with do_sync_read(). In this function we call "filp->f_op->aio_read" unconditionally. where most of the times aio_read is intialized as generic_file_aio_read(). Wouldn't it be a good idea to change the following code 241 for (;;) { 242 ret = filp->f_op->aio_read(&kiocb, &iov, 1, kiocb.ki_pos); 243 if (ret != -EIOCBRETRY) 244 break; 245 wait_on_retry_sync_kiocb(&kiocb); to 241 for (;;) { 242 if(filp->f_op->aio_read) 243 ret = filp->f_op->aio_read(&kiocb, &iov, 1, kiocb.ki_pos); 244 else 245 ret = generic_file_aio_read(&kiocb, &iov, 1, kiocb.ki_pos); 246 if (ret != -EIOCBRETRY) 247 break; 248 wait_on_retry_sync_kiocb(&kiocb); Just to have a fall back mechanism as we do at many places in the VFS layer.. -- Thanks & Regards, ******************************************** Manish Katiyar ( http://mkatiyar.googlepages.com ) 3rd Floor, Fair Winds Block EGL Software Park Off Intermediate Ring Road Bangalore 560071, India *********************************************** - To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
