[PATCH 00/11] FSMonitor Preliminary Commits

This patch series fixes runtime errors in t/perf/p7519 on Windows and MacOS. It adds Trace2 logging to p7519 to make it easier to compare results when Watchman is enabled and disabled. And finally, it adds some Trace2 regions and data events around our usage of Watchman and the existing FSMonitor framework.

This series is independent of the "Simple IPC" series.

A future series to add a builtin FSMonitor daemon will build upon both of these series.

Jeff Hostetler (10):
  p7519: use xargs -0 rather than -d in test
  p7519: fix watchman watch-list test on Windows
  p7519: move watchman cleanup earlier in the test
  p7519: add trace logging during perf test
  preload-index: log the number of lstat calls to trace2
  read-cache: log the number of lstat calls to trace2
  read-cache: log the number of scanned files to trace2
  fsmonitor: log invocation of FSMonitor hook to trace2
  fsmonitor: log FSMN token when reading and writing the index
  fsmonitor: refactor initialization of fsmonitor_last_update token

Kevin Willford (1):
  fsmonitor: allow all entries for a folder to be invalidated
