Hello,
I'm writing a scsi character device drivers and
allocate the dynamic major number. The driver went
through init_module, register_chrdev, ....attach and
MKDEV, they all appeared fine. The /proc/devices
indicated the major number 254 was assigned to the
driver afterwards. However, the "ls -l /dev/xxx"
indicates a huge major (8 to 9 digits) number and no
minor number. In addition, there is no "c" in the 1st
column.
I assigned the acquired major number to my
dd_template.major, or leave it as 0 and it does not
make any difference. And the flags in the template
indicates character driver.
Help ...
