dynamic memory allocation and swapping

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello,

    When allocating memory with kernel functions such
as kmalloc, vmalloc, and __get_free_page(s), do these
functions return memory (or pages in the case of
_get_free_page(s)) that is not eligible for swapping
to disk, or must I explicitly lock the pages in
memory.  Also, is the term 'pageable' synonymous with
'eligible for swapping'.  Any help is greatly
appreciated.  Thanks.
