Ok, I've changed the merge commit as follows now:

    Merge tag 'v4.20-rc1'

    Pull in the gfs2 fixes that went into v4.19-rc8:

      gfs2: Fix iomap buffered write support for journaled files
      gfs2: Fix iomap buffered write support for journaled files (2)

    Without these two commits, the following fix would cause conflicts.

So merging v4.19-rc8 would have been sufficient. v4.20-rc1 is what I
ended up testing, though.

Are you okay with that now?

Thanks,
Andreas
