[GIT PULL] Btrfs fixes for 6.3-rc2

[David Sterba]

Hi,

first batch of fixes. Among them there are two updates to sysfs and
ioctl which are not strictly fixes but are used for testing so there's
no reason to delay them.

Please pull, thanks.

* fix block group item corruption after inserting new block group

* fix extent map logging bit not cleared for split maps after dropping
  range

* fix calculation of unusable block group space reporting bogus values
  due to 32/64b division

* fix unnecessary increment of read error stat on write error

* improve error handling in inode update

* export per-device fsid in DEV_INFO ioctl to distinguish seeding
  devices, needed for testing

* allocator size classes
  * fix potential dead lock in size class loading logic
  * print sysfs stats for the allocation classes
