Hi Andrew,

I hope you've had a chance to review this patchset. I was wondering if you
had any concerns about merging it, or if there's anything I need to address.

Thanks,
Martin

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.

  mm/page_alloc: Add trace event for per-zone watermark setup
  mm/page_alloc: Add trace event for per-zone lowmem reserve setup
