Hi!
I've an user of my virtual cd kernel module who does get an
/* Defined for TUX async IO */
#define EWOULDBLOCKIO 530 /* Would block due to block-IO */
if he does following:
mount -t iso9660 /dev/virtualcd0 /mnt/virtualcd/
my code looks following in that part
position = startposition + offset;
desc.written = 0;
desc.count = 512 * req->current_nr_sectors;
desc.buf = req->buffer;
desc.error = 0;
do_generic_file_read(vc->vc_backing_file, &position,
&desc, vc_read_actor);
retval = desc.written;
if (!retval){
retval = desc.error;
#ifdef VC_DEBUG
printk(KERN_INFO "retval error %i\n", retval);
#endif
return retval;
}
I was now told that, that may happens if the uses passes O_NDELAY or
O_NONBLOCK in the open(2) function, but I don't see how he could do that,
with that commandline. Any ideas at that topic?
