--- Comment #20 from Eric Whitney (enwlinux@...il.com) ---
4.20 contains patches that correct delalloc cluster accounting for bigalloc
file systems.  They were merged at the beginning of the release cycle. See
"ext4: generalize extents status tree search functions" (ad431025aecd) and the
following five patches.  They should address all the problems described in this
bugzilla.

Any independent testing would be appreciated.  I'd recommend working with the
latest mainline rc available at this time, which is 4.20-rc6.
