The patchset at https://lore.kernel.org/linux-xfs/20201103150642.2032284-1-chandanrlinux@xxxxxxxxx/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@xxxxxxxxx/. 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.
