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 ------------------------------------------------------------------------------------------------------------------------------- [ C-DAC is on Social-Media too.
