Where are processes stored in Linux?
In linux, the “process descriptor” is struct task_struct [and some others]. These are stored in kernel address space [above PAGE_OFFSET ] and not in userspace. This is more relevant to 32 bit kernels where PAGE_OFFSET is set to 0xc0000000. Also, the kernel has a single address space mapping of its own.
