file entry in v2.6.39.4. Where is S?
I’m working on system calls in linux with source code version 2.6.39.4.
The book says that the system call is at entry. S implementation, located in arch/i386/kernel/entry. S，
But I can’t find the file in v2.6.39.4.
So which file implements the system call in my version? Is there any difference from the old one?
Solution
The information in your book seems outdated.
You should find what you’re looking for in arch/x86/kernel/entry_32.S and arch/x86/kernel/entry_64.S.
