This patchset introduces tracepoints to track changes in the lowmem
reserves, watermarks and totalreserve_pages. This helps to track
the exact timing of such changes and understand their relation to
reclaim activities.

The tracepoints added are:

mm_setup_per_zone_lowmem_reserve
mm_setup_per_zone_wmarks
mm_calculate_totalreserve_pagesi

Changes in V2:
  Fix coding format error. Feedback from kaleshsingh@google.com.

Martin Liu (3):
  mm/page_alloc: Add trace event for per-zone watermark setup
  mm/page_alloc: Add trace event for per-zone lowmem reserve setup
  mm/page_alloc: Add trace event for totalreserve_pages calculation
