[PATCH 0/2 -mmotm] oom: show single slab cache in oom whose size > 10% of total system memory

From: Yang Shi
Date: Wed Oct 25 2017 - 18:49:36 EST



Per the suggestion from David [1], this implementation dumps single slab cache if its size is over 10% of total system memory. In current implementation, the ration is fixed as 10%.

To get the size of total system memory patch #1 extract the common code from show_mem() so that the code can be used by checking the ratio.

The patchset is based on the mmotm tree.
