From 16070428d389ff47aa3476b0911179ad90c640a2 Mon Sep 17 00:00:00 2001 From: Jens Axboe Date: Fri, 16 Jun 2006 07:46:37 +0200 Subject: [PATCH] fix cdrom open Some time ago the cdrom open routine was changed so that we call the driver's open routine before checking to see if it is read only. However, if we discovered that a read write open was not possible and the open flags required a writable open, we just returned -EROFS without calling the driver's release routine. This seems to work for most cdrom drivers, but breaks the Powerpc iSeries virtual cdrom rather badly. This just inserts the release call in the error path to balance the call to "->open()" done by "open_for_data()".

First, netconsole poll routine shouldn't run unless the device is up; second, the NAPI poll should be disabled during suspend. This is only an issue on sky2, because it has to have one NAPI poll routine for both ports on dual port boards. Normal drivers use netif_rx_schedule_prep and that checks for netif_running.
