[PATCH 0/2] RFC: O_TMPFILE tests

[Christoph Hellwig]

This series adds a generic and one xfs-specific test for the O_TMPFILE
functionality.  For now it's purely RFC as there is no infrastructure
to test the filesystem and xfs_io supports O_TMPFILE yet, as I plan to
implement that ontop of Lukas' refactoring of the related feature
checks.

Even with these tests not going in ASAP having them out and waiting to
be merged is enough that I'd be fine with merging the tmpfile branch
into for-next so that it can go into the 3.15 merge window.
