Is there any reason why FS doesn't call dev_open during the mount system call, and analogously, dev_close on umount? Some devices might need initializations and this hook would make life easier for those who want to implement trackbuffering: - flush track buffers o dsk_close - invalidate track buffers on dsk_open If dev_open and dev_close are called upon mount/umount, there would be only one place left in the FS to be changed for trackbuffering: forward a sync() call to the driver to get the track buffers flushed.
