| H A D | seq_file.c | diff e075f591 Fri Mar 23 16:02:55 MDT 2012 KAMEZAWA Hiroyuki <kamezawa.hiroyu@jp.fujitsu.com> seq_file: add seq_set_overflow(), seq_overflow() It is undocumented but a seq_file's overflow state is indicated by m->count == m->size. Add seq_set_overflow() and seq_overflow() to set/check overflow status explicitly. Based on an idea from Eric Dumazet.
