It then uses sigaction again to fetch the information about the same signal handler, and check that they are consistent. This is enough to detect mismatches between struct kernel_sigaction and the kernel version of struct sigaction, like in BZ #23069. Changelog: * signal/tst-sigaction.c: New file to test BZ #23069. * signal/Makefile (tests): Fix indentation.
