• 0e689d036   f2fs: add key functions for f2fs_io_tracer ... Browse Code »

  This patch adds two key functions to trace process ids and IOs.
  The basic idea is to
  1. remain process ids, pids, in page->private.
  2. show pids in IO traces.

  So, later we can retrieve process information according to IO traces.
