Re: [PATCH 2.4.31] e1000: unlock tx_lock before return

Hi all.

Sorry for replying to my own post. I rediffed the patch to make it a -p1
patch as described by DaveM in another (netdev) thread. Also CC'd lkml.

lkml'ers, please CC replies to me, since I'm not subscribed.

It may happen that the e1000 driver returns from e1000_xmit_frame()
while still holding the tx_lock spinlock. This is at least true for the
version that comes with kernel 2.4.31. The problem doesn't exist in
2.6.11.12.

The attached patch applies to vanilla 2.4.31. I couldn't test the patch
myself (no e1000 available), but it's a trivial patch and thus it's
expected to work without problems.
