From: Anna Schumaker <Anna.Schumaker@Netapp.com>

I've been scratching my head about what's going on with xfstests generic/091
and generic/263, but I'm not sure what else to look at at this point.
This patchset disables READ_PLUS by default by marking it as a
developer-only kconfig option.

I also included a couple of patches fixing some other issues that were
noticed while inspecting the code. These patches don't help the tests
pass, but they do fail later on after applying so it does feel like
progress.

I'm hopeful the remaning issues can be worked out in the future.

Thanks,
Anna
