Adding 'name' key types
Playing around with the [wonderful] GSS-API patches for OpenSSH [1] I
noticed that there is a bit of functionality missing from
OpenSSH/GSS-API, namely that authorized_keys2 has no meaning when using
GSS authentication.
Yes, ~/.k5login can be used to grant access to an account for
applications that support Kerberos, as does OpenSSH with those GSS
patches, but .k5login does not and cannot provide

[PATCH net-next v4 1/6] net: allow > 0 order atomic page alloc in skb_page_frag_refill
skb_page_frag_refill currently permits only order-0 page allocs
unless GFP_WAIT is used. Change skb_page_frag_refill to attempt
higher-order page allocations whether or not GFP_WAIT is used. If
memory cannot be allocated, the allocator will fall back to
successively smaller page allocs (down to order-0 page allocs).
This change brings skb_page_frag_refill in line with the existing
page allocation

[PATCH net-next v5 0/6] virtio-net: mergeable rx buffer size auto-tuning
The virtio-net device currently uses aligned MTU-sized mergeable receive
packet buffers. Network throughput for workloads with large average
packet size can be improved by posting larger receive packet buffers.
However, due to SKB truesize effects, posting large (e.g, PAGE_SIZE)
buffers reduces the throughput of workloads that do not benefit from GRO
and have no large inbound packets.

[PATCH net 0/9] several fixups for virtio-net XDP
Merry Xmas and a Happy New year to all:
This series tries to fixes several issues for virtio-net XDP which
could be categorized into several parts:
- fix several issues during XDP linearizing
- allow csumed packet to work for XDP_PASS
- make EWMA rxbuf size estimation works for XDP
- forbid XDP when GUEST_UFO is support
- remove big packet XDP support
- add XDP support or small buffer
Please

[PATCH 00/37] [RFC] revamped modeset locking
Hi all,
First thing first: It works, I now no longer have a few dropped frames every 10s
on my testbox here with the pageflip i-g-t tests.
Random notes:
- New design has per-crtc locks to protect the crtc input-side (pageflip,
cursor) for r/w and the output state of the crtc (mode, dpms) as read-only. It
also required completely revamped fb lifecycle management, those are now
refcounted
