Hello all,
I am using Ubuntu-12.04 which came with 3.2 kernel. Parallel to this,
I've compiled and installed 3.12.1 kernel using the Ubuntu-3.2's
configuration, and the compiler which came with the distro. I've noticed
that there is a huge difference in the size of the .ko file between the
Ubuntu's kernel and the kernel which I've compiled. Sample results are :
$ du -sh usb-storage.ko
It shows : 56K for the Ubuntu's 3.2 kernel
1.3M for the custom kernel that I've compiled
I've tested the same thing for a simple hello world module :
$ du -sh hello.ko
It shows : 4.0k for the Ubuntu's 3.2 kernel
56k for the custom kernel that I've compiled
What could be the reason for this huge amount of difference of storage
space in spite of using the same config file and compiler?
Thanks in advance.
Raghavendra
