Linux's SystemV Filesystem Support Being Orphaned

Linux developer Christoph Hellwig who had been listed as the maintainer of the SystemV file-system code has decided to orphan it so within the kernel source tree it will now be marked as being unmaintained.
Hellwig wrote on the patch orphaning this old file-system support:
"This code has been stale for years and I have no way to test it."
Those curious about the current SystemV Filesystem support with the Linux kernel can see the kernel documentation.
For now this file-system support is staying put in the kernel -- albeit stale -- but without someone willing to maintain it runs the risk of further code rot and removal in the future.
