There's two ways to deal with it, one ugly and quick and one to do it right. The quick hack is to fake up a file struct similar to blkdev_get(). The proper solutions is to get rid of the file (and inode) in the blockdev ->ioctl prototype. Only thing keeping is from that is floppy.c (and some cut & paste variants for m68k) due to their awkard permission checking hacks. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | ||||||||||
