net: Delete trailing semi-colon from definition of netdev_WARN()
Macro definitions should not normally end with a semi-colon, as this
makes it dangerous to use them an if...else statement. Happily this
has not happened yet.

net: refactor sk_page_frag_refill()
While working on virtio_net new allocation strategy to increase
payload/truesize ratio, we found that refactoring sk_page_frag_refill()
was needed.
This patch splits sk_page_frag_refill() into two parts, adding
skb_page_frag_refill() which can be used without a socket.
While we are at it, add a minimum frag size of 32 for
sk_page_frag_refill()
Michael will either use netdev_alloc_frag() from softirq context,
or skb_page_frag_refill() from process context in refill_work()
(GFP_KERNEL allocations)

====================
net: ethernet: remove unnecessary pci_set_drvdata() part 1
Since commit 0998d0631001288a5974afc0b2a5f568bcdecb4d
(device-core: Ensure drvdata = NULL when no driver is bound),
the driver core clears the driver data to NULL after device_release
or on probe failure. Thus, it is not needed to manually clear the
device driver data to NULL.

f2fs: avoid wait if IO end up when do_checkpoint for better performance
Previously, do_checkpoint() will call congestion_wait() for waiting the pages
(previous submitted node/meta/data pages) to be written back.
Because congestion_wait() will set a regular period (e.g. HZ / 50 ) for waiting, and
no additional wake up mechanism was introduced if IO ends up before regular period costed.
Yuan Zhong found there is a situation that after the pages have been written back,
but the checkpoint thread still wait for congestion_wait to exit.
So here we store checkpoint task into f2fs_sb when doing checkpoint, it'll wait for IO completes
if there's IO going on, and in the end IO path, wake up checkpoint task when IO ends up.
Thanks to Yuan Zhong's pre work about this problem.
