由 Bjorn Helgaas 提交于
Remove the assumption that driver_register() returns the number of devices bound to the driver. In fact, it returns zero for success or a negative error value. zorro_module_init() used the device count to automatically unregister and unload drivers that found no devices. That might have worked at one time, but has been broken for some time because zorro_register_driver() returned either a negative error or a positive count (never zero). So it could only unregister on failure, when it's not needed anyway. This functionality could be resurrected in individual drivers by counting devices in their .probe() methods.

Don't free transmit buffers until the whole set of transmit descriptors has been marked as done. Otherwise, we risk freeing a skb before the whole transmit is done. This changes the transmit completion handling from incremental to a two pass algorithm. First pass scans and records the start of the last done descriptor, second cleans up until that point.

The skge driver was using dev_alloc_skb which reserves space for the Ethernet header. This unnecessary and it should just use alloc_skb, also by using GFP_KERNEL during startup it won't run into problems when a user asks for a huge ring size or mtu and potentially drains the reserved atomic pool.

Observed problems when multiple processes request scans and subsequently scan results. This causes a scan result request to hit card registers before the scan is complete, returning an incomplete scan list and possibly making the card very angry. Instead, cache the results of a wireless scan and serve result requests from the cache, rather than hitting the hardware for them.

When we stop allocating percpu memory for not-possible CPUs we must not touch the percpu data for not-possible CPUs at all. The correct way of doing this is to test cpu_possible() or to use for_each_cpu(). This patch is a kernel-wide sweep of all instances of NR_CPUS. I found very few instances of this bug, if any. But the patch converts lots of open-coded test to use the preferred helper macros.

This is version 20 of the Wireless Extensions. This is the completion of the RtNetlink work I started early 2004, it enables the full Wireless Extension API over RtNetlink. Few comments on the patch : o totally driver transparent, no change in drivers needed. o iwevent were already RtNetlink based since they were created (around 2.5.7). This adds all the regular SET and GET requests over RtNetlink, using the exact same mechanism and data format as iwevents. o This is a Kconfig option, as currently most people have no need for it. Surprisingly, patch is actually small and well encapsulated. o Tested on SMP, attention as been paid to make it 64 bits clean. o Code do probably too many checks and could be further optimised, but better safe than sorry. o RtNetlink based version of the Wireless Tools available on my web page for people inclined to try out this stuff. I would also like to thank Alexey Kuznetsov for his helpful suggestions to make this patch better. Signed-off-by: NJean Tourrilhes <jt@hpl.hp.com> Signed-off-by: NJohn W.
