[GIT PULL] Btrfs updates for 5.6, part 2

[GIT PULL] Btrfs updates for 5.6, part 2

[David Sterba]

Hi,

second batch containing fixes that arrived after the merge window
freeze, mostly stable material. The top patch is fresh but addressing
space reporing bug that's been bothering users and we've tested it
meanwhile.

Please pull thanks.

* fix race in tree-mod-log element tracking

* fix bio flushing inside extent writepages

* fix assertion when in-memory tracking of discarded extents finds an
  empty tree (eg. after adding a new device)

* update logic of temporary read-only block groups to take into account
  overcommit

* fix some fixup worker corner cases:
  - page could not go through proper COW cycle and the dirty status is
    lost due to page migration
  - deadlock if delayed allocation is performed under page lock

* fix send emitting invalid clones within the same file

* fix statfs reporting 0 free space when global block reserve size is
  larger than remaining free space but there is still space for new
  chunks
