From cc054c6f139cf54ce8fbefd6fd536f50b4cba694 Mon Sep 17 00:00:00 2001 From: Helge Deller Date: Sun, 18 Sep 2022 21:45:46 +0200 Subject: linux-user: Add pidfd_open(), pidfd_send_signal() and pidfd_getfd() syscalls I noticed those were missing when running the glib2.0 testsuite. Add the syscalls including the strace output.
