[PATCH] Fix for LKDTM MEM_SWAPOUT crashpoint
The MEM_SWAPOUT crashpoint in LKDTM could be broken as some compilers inline the call to shrink_page_list() and symbol lookup for this function name fails. Replacing it with the function shrink_inactive_list(), which is the only function calling shrink_page_list().
