[PATCH liburing v2 0/7] run tests in parallel

[Dylan Yudaken <dylany@fb.com>]

This series allows tests to be run in parallel, which speeds up
iterating. Rather than build this functionality into the shell scripts, it
seemed much easier to use make's parallel execution to do this.

My bash/make skills are not top notch, so I might have missed something
obvious, however it does seem to work locally very nicely.


Patch #1 is a bug that seems to trigger quite often when running in parallel
Patch #2-5 fix bugs that prevent tests running in parallel
Patch #6 adds a make target that depends on running each test
Patch #7 Is not related to parallel tests. It is a prep for a later series to use nop to test IOPOLL.

v2:
 - fix runtests-quiet.sh to return the correct error code
 - add runtests-parallel to the main target

Dylan Yudaken (7):
  test: handle mmap return failures in pollfree test
  test: use unique path for socket
  test: use unique ports
  test: use unique filenames
  test: mkdir -p output folder
  test: add make targets for each test
  test: use remove_buffers instead of nop to generate error codes
