( https://review.gerrithub.io/c/ffilz/nfs-ganesha/+/487898 ) Change subject: MDCACHE - Close unexport race for used entries ...................................................................... MDCACHE - Close unexport race for used entries When we're unexporting, we need to make an entry unreachable if no exports are referencing it. However, the refcount is not a suitable method of determining this, since an OP can be outstanding on the entry, keeping a ref on it. If this was the case, we'd leave the entry dangling, and a new export could reference it, and it's contents could be bad. To avoid this, switch from using the refcount to a locked check to make sure the entry is still not exported.
