Subject: Fix for LKDTM MEM_SWAPOUT crashpoint
From: Ankita Garg <ankita@xxxxxxxxxx>
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().
