[GIT PULL] Btrfs fixes for 5.6-rc2

[David Sterba <dsterba@suse.com>]

Hi,

please pull the following mix of fixes. There are two races fixed,
memory leak fix, sysfs directory fixup and two new log messages.

* two fixed race conditions: extent map merging and truncate vs fiemap

* create the right sysfs directory with device information and move the
  individual device dirs under it

* print messages when the tree-log is replayed at mount time or cannot
  be replayed on remount

Thanks.
