I added this as well: static inline char *format_dev_t(char *buffer, dev_t dev) { sprintf(buffer, "%04lx\n", (unsigned long)dev); return buffer; } tp be placed direct in a printk(). We'll probably need to do something more fancy in here later, because once a dev_t becomes 32:32, it'll need to be printed out with "%016llx", which is daft. So we'll need to come up with some standardised way of presenting a dev_t to the user. Presumably that will just be sprintf(buf, "%d:%d", major(dev), minor(dev)); But if we do this, will it break your existing stuff? > If I should put the print_dev_t() function in a different header file, > please let me know. Seems OK. Every kdev_t.h includer now needs to include kernel.h too.
