* procargs.c: (glibtop_get_proc_args_s): * prockernel.c: (glibtop_get_proc_kernel_s): * procmem.c: (glibtop_get_proc_mem_s): * procsegment.c: (glibtop_get_proc_segment_s): * procsignal.c: (glibtop_get_proc_signal_s): * procstate.c: (glibtop_get_proc_state_s): * proctime.c: (glibtop_get_proc_time_s): * procuid.c: (glibtop_get_proc_uid_s): No longer abort() is no such pid. buf.flags == 0ULL means that there no data could be retrieve at all. Closes #154876. Thanks to Christophe Belle.
