LRU pagevec holds refcount of pages until the pagevec are drained.
It could prevent migration since the refcount of the page is greater
than the expection in migration logic. To mitigate the issue,
callers of migrate_pages drains LRU pagevec via migrate_prep or

Pages containing buffer_heads that are in one of the per-CPU
buffer_head LRU caches will be pinned and thus cannot be migrated.
This can prevent CMA allocations from succeeding, which are often used

series from a year ago as they weren't picked up. The other patches are
already merged, so I didn't resend them. They still apply as-is, so no changes
are made.
Changes from v2:
* Collected acked-by.
Original cover letter:
The Topwise A721/LY-F1 tablet is a tablet sold around 2012 under
different brands. The mainboard mentions A721 clearly, so this tablet
is best known under this name.

Hi,

For the other parts, the question is what we actually want to let
user space configure.
Being able to specify "Very secure" "maximum secure" "average
secure" all doesn't really make sense to me.
Well, it doesn't to me either unless the user feels a cost/benefit, so

This series introduces XSK generic zerocopy xmit by adding XSK umem
pages as skb frags instead of copying data to linear space.
The only requirement for this for drivers is to be able to xmit skbs
with skb_headlen(skb) == 0, i.e. all data including hard headers
starts from frag 0.
To indicate wheth

I wonder if we could find a better name for the configure switch.
I have troubles to imagine what printk enumeration might mean.
Well, it might be because I am not a native speaker.
Anyway, the word "enumeration" is used only in the configure option.
Everything else is "print

We almost ran out of unsigned int bitwidth. Define priv flags and
check for potential overflow in the fashion of netdev_features_t.
Defined this way, priv_flags can be easily expanded later with
just changing its typedef.

In some cases, we hope to construct skb directly based on the existing
memory without copying data. In this case, the page will be placed
directly in the skb, and the linear space of skb is empty. But
unfortunately, many the network card does not support this operation.

xsk_generic_xmit() allocates a new skb and then queues it for
xmitting. The size of new skb's headroom is desc->len, so it comes
to the driver/device with no reserved headroom and/or tailroom.
Lots of drivers need some headroom (and sometimes tailroom) to

This patch is used to construct skb based on page to save memory copy
overhead.
This function is implemented based on IFF_TX_SKB_NO_LINEAR. Only the
network card priv_flags supports IFF_TX_SKB_NO_LINEAR will use page to
directly construct skb. If this feature is not supported, it
