linD026	eef2bc4395	Enforce Linux kernel coding style (#88) ... The only exception is to indent with four spaces rather than tabs for sticking to compact layout of source listing. Close #87	2021-09-02 15:15:07 +08:00
linD026	06b75942cc	Fix incorrect major number registration in chardev (#77) ... chardev2.c demonstrates the ioctl operation with static major number MAJOR_NUM, but there also exists "Major," the dynamic one, which results in registration and deregistration on different device. Once the module remove, it cannot insert again: $ sudo insmod chardev2.ko $ sudo rmmod chardev2 $ cat /proc/devices Character devices: ... 100 char_dev $ sudo insmod chardev2.ko insmod: ERROR: could not insert module chardev2.ko: Device or resource busy This patch removed the use of dynamic major number.	2021-08-26 03:16:17 +08:00
