2010-11-11net: get rid of rtable->idevEric Dumazet
It seems idev field in struct rtable has no special purpose, but adding extra atomic ops. We hold refcounts on the device itself (using percpu data, so pretty cheap in current kernel). infiniband case is solved using dst.dev instead of idev->dev Removal of this field means routing without route cache is now using shared data, percpu data, and only potential contention is a pair of atomic ops on struct neighbour per forwarded packet. About 5% speedup on routing test.

2010-11-11vxge: correct multi-function detectionJon Mason
The values used to determined if the adapter is running in single or multi-function mode were previously modified to the values necessary when making the VXGE_HW_FW_API_GET_FUNC_MODE firmware call. However, the firmware call was not modified. This had the driver printing out on probe that the adapter was in multi-function mode when in single function mode and vice versa.

Wait for the receive traffic to become idle before attempting to close or reset the adapter. To enable the processing of packets while Receive Idle, move the clearing of __VXGE_STATE_CARD_UP bit in vxge_close to after it. Also, modify the return value of the ISR when the adapter is down to IRQ_HANDLED. Otherwise there are unhandled interrupts for the device.

2010-11-06floppy: fix another use-after-freeVivek Goyal
While scanning the floopy code due to c093ee4f07f4 ("floppy: fix use-after-free in module load failure path"), I found one more instance of trying to access disk->queue pointer after doing put_disk() on gendisk. For some reason , floppy moule still loads/unloads fine. The object is probably still around with right pointer values. o There seems to be one more instance of trying to cleanup the request queue after we have called put_disk() on associated gendisk. o This fix is more out of code inspection. Even without this fix for some reason I am able to load/unload floppy module without any issues. o Floppy module loads/unloads fine after the fix.

2010-11-05ipw2x00: remove the right /proc/net entryLinus Torvalds
Commit 27ae60f8f7aa ("ipw2x00: replace "ieee80211" with "libipw" where appropriate") changed DRV_NAME to be "libipw", but didn't properly fix up the places where it was used to specify the name for the /proc/net/ directory. For backwards compatibility reasons, that directory name remained "ieee80211", but due to the DRV_NAME change, the error case printouts and the cleanup functions now used "libipw" instead. Which made it all fail badly. For example, on module unload as reported by Randy: WARNING: at fs/proc/generic.c:816 remove_proc_entry+0x156/0x35e() name 'libipw' because it's trying to unregister a /proc directory that obviously doesn't even exist.
