I'v found that directory /usr/include/linux includes some files that not included by directory <include/linux> of kernel source, why is that?
/usr/include/linux is the directory for header files used by user space applications whereas include/linux of kernel_source is for kernel and both directories can't keep same header files due to their usage difference like kernel_source include/linux has function declarations for functions used directly by kernel it-self but the /usr/include/linux contains only declarations/structures for those used by the user_space library (like glibc)
Do some other programs put headers in directory /usr/include/linux?
/usr/include/linux is for user_space applications/programs and some other program can keep its files in it, but I think its not recommended -- Fawad Lateef -- Kernelnewbies: Help each other learn about the Linux kernel.
