Subject: [GIT PULL] iomap: fixes for 5.5

Hi Linus,

Please pull these iomap bug fixes for 5.5-rc1, which fix a race
condition and a use-after-free error.

The branch has survived overnight xfstests runs and merges cleanly with
this morning's master.  Please let me know if anything strange happens.

--D
