This allows process # managers to know when a (non-parent) process dies in a race-free # way. # # The notification mechanism used follows the same logic that is # currently used when the parent of a task is notified of a child's # death. With this patchset it is possible to put pidfds in an # {e}poll loop and get reliable notifications for process (i.e. # thread-group) exit. # # - The second feature compliments the first one by making it possible # to retrieve pollable pidfds for processes that were not created # using CLONE_PIDFD. # # A lot of processes get created with traditional PID-based calls # such as fork() or clone() (without CLONE_PIDFD). For these # processes a caller can currently not create a pollable pidfd. This # is a problem for Android's low memory killer (LMK) and service # managers such as systemd. # # Both patchsets are accompanied by selftests. # # It's perhaps worth noting that the work done so far and the work done # in this branch for pidfd_open() and polling support do already see # some adoption: # # - Android is in the process of backporting this work to all their LTS # kernels [1] # # - Service managers make use of pidfd_send_signal but will need to # wait until we enable waiting on pidfds for full adoption. # # - And projects I maintain make use of both pidfd_send_signal and # CLONE_PIDFD [2] and will use polling support and pidfd_open() too" # # [1] https://android-review.googlesource.com/q/topic:%22pidfd+polling+support+4.9+backport%22 #
