Revision 56a86f84b8332afe8c6fcb4b09d09d9bf094e2db authored by Jason Wang on 23 December 2016, 14:37:26 UTC, committed by David S. Miller on 23 December 2016, 18:48:54 UTC
We don't put page during linearizing, the would cause leaking when
xmit through XDP_TX or the packet exceeds PAGE_SIZE. Fix them by
put page accordingly. Also decrease the number of buffers during
linearizing to make sure caller can free buffers correctly when packet
exceeds PAGE_SIZE. With this patch, we won't get OOM after linearize
huge number of packets.
