Merge git://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf
Daniel Borkmann says: ==================== pull-request: bpf 2018-06-12 The following pull-request contains BPF updates for your *net* tree. The main changes are: 1) Avoid an allocation warning in AF_XDP by adding __GFP_NOWARN for the umem setup, from Björn. 2) Silence a warning in bpf fs when an application tries to open(2) a pinned bpf obj due to missing fops. Add a dummy open fop that continues to just bail out in such case, from Daniel. 3) Fix a BPF selftest urandom_read build issue where gcc complains that it gets built twice, from Anders. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
