[PATCH 0/2] coredump: Allow io_uring using apps to dump to pipes.

[Eric W. Biederman]

Folks who have been suffering from io_uring coredumping issues please
give this a spin.  I have lightly tested this version and more heavily
tested an earlier version which had more dependencies.

Unless I have missed something in cleaning up the code this should
be a comprehensive fix to the coredumping issues when using io_uring.

But folks please test and verify this.  It has taken me long enough to
get back to this point I don't properly remember how the reproducer I
have was supposed to fail.  All I can say with certainty is set of
changes has what looks like a positive effect.

      signal: Move stopping for the coredump from do_exit into get_signal
      coredump: Allow coredumps to pipes to work with io_uring
