#     Merge tag 'pidfd-fixes-v5.1-rc3' of gitolite.kernel.org:pub/scm/linux/kernel/git/brauner/linux
#     
#     Pull pidfd fix from Christian Brauner:
#      "This should be an uncontroversial fix for pidfd_send_signal() by Jann
#       to better align it's behavior with other signal sending functions:
#     
#       In one of the early versions of the patchset it was suggested to not
#       unconditionally error out when a signal with SI_USER is sent to a
#       non-current task (cf. [1]).
#     
#       Instead, pidfd_send_signal() currently silently changes this to a
#       regular kill signal. While this is technically fine, the semantics are
#       weird since the kernel just silently converts a user's request behind
#       their back and also no other signal sending function allows to do
#       this. It gets more hairy when we introduce sending signals to a
#       specific thread soon.
#     
#       So let's align pidfd_send_signal() with all the other signal sending
#       functions and error out when SI_USER signals are sent to a non-current
#       task"
#
