ll_rw_blk.c: generic_make_request() contains the following code:
if (maxsector < count || maxsector - count < sector) { bh->b_state &= (1 << BH_Lock) | (1 << BH_Mapped); if (blk_size[major][MINOR(bh->b_rdev)]) {
/* This may well happen - the kernel calls bread() without checking the size of the device, e.g., when mounting a device. */ printk(KERN_INFO "attempt to access beyond end of device\n"); printk(KERN_INFO "%s: rw=%d, want=%d, limit=%d\n", kdevname(bh->b_rdev), rw, (sector + count)>>1, blk_size[major][MINOR(bh->b_rdev)]); } bh->b_end_io(bh, 0); return; }
That means that if blk_size[major][MINOR(bh->b_rdev)] == 0, the request is canceled but no message is printed. Shouldn't there be a warning message?
