buffermem_pages removal (3/5)
PATCH 1/1 buffermem_pages removal (3/5)
This one is a bit more controveral as it may break stupid userlevel
programs: remove the 'Buffers' field from /proc/meminfo and make the Cached field show the full pagecache size instead of subtracting the block-device backed pages.
All /proc/meminfo-using programs I have (free, top) still work fine.
