Subject: [PATCH 0/4] btrfs: Convert more kmaps to kmap_local_page()

From: Ira Weiny <ira.weiny@...el.com>

I am submitting these for 5.13.

Further work to remove more kmap() calls in favor of the kmap_local_page() this
series converts those calls which required more than a common pattern which
were covered in my previous series[1].  This is the second of what I hope to be
3 series to fully convert btrfs.  However, the 3rd series is going to be an RFC
because I need to have more eyes on it before I'm sure about what to do.  For
now this series should be good to go for 5.13.

Also this series converts the kmaps in the raid5/6 code which required a fix to
the kmap'ings which was submitted in [2].

Thanks,
Ira
