Hello:

This patch was applied to netdev/net-next.git (master)

To work around a misbehavior of the compiler's ability to see into

bounds-checking, and allocation are all very tightly coupled here.
This silences the false-positive reported by syzbot:

  memcpy: detected field-spanning write (size 80) of single field "&n->sel" at net/sched/cls_u32.c:1043 (size 16)
