Date: Sat, 10 Mar 2007 02:31:22 -0200 From: Mauro Carvalho Chehab <mchehab@...radead.org> To: rusty@...tcorp.com.au Cc: Trent Piepho <xyzzy@...akeasy.org>, Rechberger Markus <mrechberger@...il.com>, Linux DVB <linux-dvb@...uxtv.org>, David Woodhouse <dwmw2@...radead.org>, Andrew Morton <akpm@...ux-foundation.org>, LKML <linux-kernel@...r.kernel.org> Subject: [RFC PATCH 0/3] Fix module information when symbol_get is used Hi Rusty, DVB code uses symbol_get/symbol_put functions at module.c to allow dynamically add frontend modules (responsible for tuning and demodulating the digital signal). The problem is that symbol_get doesn't properly mark the module that requested it. Trent worked on a fix for this, by using 3 patches. One on module.c, another on mtd driver, and the last one on linux-dvb. With the patch, lsmod produces output like this: cx88_dvb 14084 0 or51132 9988 1 cx88_dvb Without it, this is what you get: cx88_dvb 14084 0 or51132 9988 1 drivers/media/dvb/bt8xx/dst.c | 5 - drivers/media/dvb/dvb-core/dvb_frontend.c | 9 +-- drivers/mtd/chips/gen_probe.c | 4 - include/linux/module.h | 13 ++-- kernel/module.c | 87 ++++++++++++++++++++++-------- 5 files changed, 80 insertions(+), 38 deletions(-) - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
