[PATCH] net: Ignore sysfs network device rename bugs.
The generic networking code ensures that no two networking devices have the same name, so there is no time except when sysfs has implementation bugs that device_rename when called from dev_change_name will fail. The current error handling for errors from device_rename in dev_change_name is wrong and results in an unusable and unrecoverable network device if device_rename is happens to return an error. This patch removes the buggy error handling. Which confines the mess when device_rename hits a problem to sysfs, instead of propagating it the rest of the network stack. Making linux a little more robust. Without this patch you can observe what happens when sysfs has a bug when CONFIG_SYSFS_DEPRECATED is not set and you attempt to rename a real network device to a name like (broken_parity_status, device, modalias, power, resource2, subsystem_vendor, class, driver, irq, msi_bus, resource, subsystem, uevent, config, enable, local_cpus, numa_node, resource0, subsystem_device, vendor) Greg has a patch that fixes the sysfs bugs but he doesn't trust it for a 2.6.21 timeframe. This patch which just ignores errors should be safe and it keeps the system from going completely wacky. Signed-off-by: Eric W.
