-stable review patch. If anyone has any objections, please let us know. --------------------- From: David S. Miller Upstream commit: da990a2402aeaee84837f29054c4628eb02f7493 As reported by Johannes Berg: I started getting this warning with recent kernels: [ 773.908927] ------------[ cut here ]------------ [ 773.908954] Badness at net/core/dev.c:2204 ... If we loop more than once in gem_poll(), we'll use more than the real budget in our gem_rx() calls, thus eventually trigger the caller's assertions in net_rx_action(). Subtract "work_done" from "budget" for the second arg to gem_rx() to fix the bug. Signed-off-by: David S.
