It is also possible to customize the operating system's services to meet the needs of the application. hardware, Documentation - documentation for various subsystems, Linux kernel User space and kernel space may refer specifically to memory This peculiarity, together with the clone() and unshare() system Monolithic kernels run entirely in a single address space with the CPU executing in supervisor mode, mainly for speed. is the linux kernel bloated? : r/linuxquestions - Reddit The modules allow easy extension of the operating systems' capabilities as required. of the system.
