SubjectRe: How many params can be accept by kernel module at most?
From
The params are transferred by command line. And the params are all in
program statically. So the stack size determine the params number. For
example: stack size is 4K,and params are unsigned int type with 4
bytes,so the max number of params is 1 thousand。
