Warning: The frame size of 1040 bytes is larger than 1024 bytes

Problem description:

When compiling the kernel module driver, the following warning message is displayed:

Warning: The frame size of 1040 bytes is larger than 1024 bytes. This is mainly because the stack alarm size is set in the kernel, Which is 1024 bytes by default. We can modify it to 4096 to eliminate alarm information.

If the solution is:

(1) make menuconfig

(2) kernel hacking

(3) modify the value of warn for Stack frames larger than to 4096 (preferably not greater than this value)

(4) recompile the kernel module without the above warning information.
