#17 (comment)

I don't do github pull requests.

github throws away all the relevant information, like having even a
valid email address for the person asking me to pull. The diffstat is
also deficient and useless.

Git comes with a nice pull-request generation module, but github
instead decided to replace it with their own totally inferior version.
As a result, I consider github useless for these kinds of things. It's
fine for hosting, but the pull requests and the online commit
editing, are just pure garbage.

I've told github people about my concerns, they didn't think they
mattered, so I gave up. Feel free to make a bugreport to github.

Thanks for this, I'll see how to make the proper PR, or discard this at all.

virtio-net: fix for unable to handle page fault for address
6c66c14 
In merge mode, when xdp is enabled, if the headroom of buf is smaller
than virtnet_get_headroom(), xdp_linearize_page() will be called but the
variable of "headroom" is still 0, which leads to wrong logic after
entering page_to_skb().

virtio-net: fix for unable to handle page fault for address
5c37711 
In merge mode, when xdp is enabled, if the headroom of buf is smaller
than virtnet_get_headroom(), xdp_linearize_page() will be called but the
variable of "headroom" is still 0, which leads to wrong logic after
entering page_to_skb().

arm64: bpf: fix 32bit unconditional bswap

[ Upstream commit a51cd6b ]

In case when is64 == 1 in emit(A64_REV32(is64, dst, dst), ctx) the
generated insn reverses byte order for both high and low 32-bit words,
resuling in an incorrect swap as indicated by the jit test:
