I wnated to kick off some testing tonight, so I've made this change to
the git tree.  So the new version of "reserve metadata block for every
delayed write" is here:

https://git.kernel.org/cgit/linux/kernel/git/tytso/ext4.git/commit/?h=dev&id=c7cf7abbf754f16b78a8b9641d06baac6be60524

... and the dev branch has been modified to drop the "reserve metadata
if writing into unitialized.." commit.
