We used to call tail_alloc(1) to create memory mapping holes around regular tail_alloc allocations. This is no longer needed since regular tail_alloc allocations create additional memory mapping holes. * tests/clock_adjtime.c (main): Remove creation of memory mapping holes using tail_alloc(1). * tests/futimesat.c (main): Likewise. * tests/get_mempolicy.c (print_nodes, main): Likewise. * tests/getgroups.c (main): Likewise. * tests/getresugid.c (main): Likewise. * tests/ioctl_uffdio.c (main): Likewise. * tests/ioctl_v4l2.c (main): Likewise. * tests/move_pages.c (main): Likewise. * tests/net-icmp_filter.c (main): Likewise. * tests/ptrace.c (test_peeksiginfo, main): Likewise. * tests/pwritev.c (main): Likewise. * tests/set_mempolicy.c (print_nodes): Likewise. * tests/setgroups.c (main): Likewise. * tests/umovestr3.c (main): Likewise. * tests/utimes.c (main): Likewise. * tests/xattr.c (main): Likewise.
