I have software that can already set a directory quota for a directory. What I would like is to have the ability to remove a directory quota from the same software.

In the VFS documentation there is a noQuota option for user space quotas, but I cannot find an equivalent for directory quotas. I have tried passing -1 as the new quota limit but that ends up setting the 'complete space restriction' option that denies any writing to the directory.

Can someone please enlighten me?
