page_is_pfmemalloc() is used mostly by networking drivers. It doesn't
write anything to the struct page itself, so constify its argument and
a bunch of callers and wrappers around this function in drivers.
In Page Pool core code, it can be simply inlined instead.
Alexander Lobakin (3):
The function only tests for page->index, so its argument should be
const.

This set addresses several near-critical issues that were observed
and reproduced on different test and production configurations.

This is likely a copy'n'paste mistake. The amount of ILT lines to
reserve for a single VF was being multiplied by the total VFs count.
This led to a huge redundancy in reservation and potential lines
drainouts.

I think it is fine to reenable this again, now that UDP sockets will
segment unexpected UDP GSO packets that may have looped. We previously
added general software support in commit 83aa025f535f ("udp: add gso

Virtual netdevs should use NETIF_F_GSO_SOFTWARE to forward GSO skbs
as-is and let the final drivers deal with them when supported.
Also remove NETIF_F_GSO_UDP_L4 from bonding and team drivers as it's
now included in the "software" list.
