Is it applicable total 1GB of kernel address space?


IMHO, it is true for only the memory which is ACTUALLY in use by the
kernel. For e.g. on a system with 512 MB RAM, if a kernel's static
memory foot print is 50 MB, then that 50 MB will never be swapped out
to disk.

Additionally, the dynamically allocated memory by the kernel (e.g. if
a driver kmallocs() certain memory) is also marked as non-swappable
(till the time it is kfreed()).

Can some body please CMIIW.

Thanks,

Rajat
