Analyze and fix the following issue in the Linux kernel code: brd: limit 'max_part' module param to DISK_MAX_PARTS
Problem Details: The 'max_part' parameter controls the number of maximum partition a brd device can have. However if a user specifies very large value it would exceed the limitation of device minor number and can cause a kernel panic (or, at least, produce invalid device nodes in some cases). On my desktop system, fol...
