commit ee55823a11b711fc4af6c3c906c341c057a414f3 Author: David Goulet dgoulet@torproject.org Date: Wed Jan 22 11:06:11 2020 -0500
mainloop: Rename global_write_bucket_low()
That function is only used to test the global bucket write limit for a directory connection.
It should _not_ be used for anything else since that function looks to see if we are a directory authority.
Rename it to something more meaningful. No change in behavior at this commit, only renaming.
Part of #33029
