[NET]: Avoid atomic xchg() for non-error case
It also looks like there were 2 places where the test on sk_err was missing from the event wait logic (in sk_stream_wait_connect and sk_stream_wait_memory), while the rest of the sock_error() users look to be doing the right thing. This version of the patch fixes those, and cleans up a few places that were testing ->sk_err directly. Signed-off-by: Benjamin LaHaise <benjamin.c.lahaise@intel.com> Signed-off-by: David S.
