The patchset at
https://lore.kernel.org/linux-xfs/20201103150642.2032284-1-chandanrlinux@gmail.com/T/#m90a8754df516bbd0c36830904a2e31c37983792c
added support to XFS to detect inode extent count overflow when
performing various filesystem operations. The patchset also added
new error injection tags for,
1. Reducing maximum extent count to 10.
2. Allocating only single block sized extents.

The corresponding code for xfsprogs can be obtained from
https://lore.kernel.org/linux-xfs/20201104114900.172147-1-chandanrlinux@gmail.com/.

The patches posted along with this cover letter add tests to verify if
the in-kernel inode extent count overflow detection mechanism works
correctly.

These patches can also be obtained from
https://github.com/chandanr/xfsprogs-dev.git at branch
extent-overflow-tests.
