We don't have swap space though we have a fs. 2) Why the the nr_free_pages and the zero reference count page frame number are so different by 1000 ~ 7500. Does this mean a bigger page cache? 3) what is the best way to find out how much space is used up user space vs the kernel space? Thanks in advance for your help.
