Date: Wed, 24 Jan 2007 00:54:05 -0200 From: Mauro Carvalho Chehab <mchehab@...radead.org> To: LKML <linux-kernel@...r.kernel.org> Cc: V4L-DVB Maintainers <v4l-dvb-maintainer@...uxtv.org>, Oleg Nesterov <oleg@...sign.ru>, Mauro Carvalho Chehab <mchehab@...radead.org> Subject: [PATCH 1/1] V4L/DVB (5123): Buf_qbuf: fix: videobuf_queue->stream corruption and lockup From: Oleg Nesterov <oleg@...sign.ru> We are doing ->buf_prepare(buf) before adding buf to q->stream list. This means that videobuf_qbuf() should not try to re-add a STATE_PREPARED buffer.
