Swift/ideas/account-quota-files
Problem
It's possible to set "X-Container-Meta-Quota-Bytes" and "X-Container-Meta-Quota-Count" on containers, as documented in the official docs. It's currently possible to configure quotas on Accounts for "quota-bytes", which is by the way not documented in the official documentation but only here. There's no way to configure account quota for "quota-count". Because of this, a user could possibly exhaust the filesystem inodes.
Proposed solution
The code https://github.com/openstack/swift/blob/master/swift/common/middleware/account_quotas.py should include a way for users with ResellerAdmin role to add a quota-count limit on accounts, and enforce such limit.
