  Move accounting tool to tools and remove it from Documentation
  Makefile. Update location information for this tool. Create a
  new Makefile to build accounting. It can be built from top level
  directory or from accounting directory:

  Run make -C tools/accounting or cd tools/accounting; make

  Update document and make getdelays.c show delay accounting for memory reclaim.

  For making a distinction between "swapping in pages" and "memory reclaim"
  in getdelays.c, MEM is changed to SWAP.

• 163ecdff0   [PATCH] delay accounting: temporarily enable by default ... Browse Code »

  Enable delay accounting by default so that feature gets coverage testing
  without requiring special measures.

  Earlier, it was off by default and had to be enabled via a boot time param.
  This patch reverses the default behaviour to improve coverage testing. It
  can be removed late in the kernel development cycle if its believed users
  shouldn't have to incur any cost if they don't want delay accounting. Or
  it can be retained forever if the utility of the stats is deemed common
  enough to warrant keeping the feature on.

• ad4ecbcba   [PATCH] delay accounting taskstats interface send tgid once ... Browse Code »

  Send per-tgid data only once during exit of a thread group instead of once
  with each member thread exit.

  Currently, when a thread exits, besides its per-tid data, the per-tgid data
  of its thread group is also sent out, if its thread group is non-empty.
  The per-tgid data sent consists of the sum of per-tid stats for all
  *remaining* threads of the thread group.

  This patch modifies this sending in two ways:

  - the per-tgid data is sent only when the last thread of a thread group
  exits. This cuts down heavily on the overhead of sending/receiving
  per-tgid data, especially when other exploiters of the taskstats
  interface aren't interested in per-tgid stats

  - the semantics of the per-tgid data sent are changed. Instead of being
  the sum of per-tid data for remaining threads, the value now sent is the
  true total accumalated statistics for all threads that are/were part of
  the thread group.

  The patch also addresses a minor issue where failure of one accounting
  subsystem to fill in the taskstats structure was causing the send of
  taskstats to not be sent at all.

  The patch has been tested for stability and run cerberus for over 4 hours
  on an SMP.
