trapexit/mergerfs 2.37.0 on GitHub

Change Summary

readdir policies: func.readdir=X where X is seq, cor, or cosr.
- seq: sequential - works same as before. Iterate over each branch in order configured.
- cosr: concurrent open sequential read - dispatches requests to open directories to a thread pool and then reads directories sequentially the same way seq does.
- cor: concurrent open and read - dispatches requests to a thread pool which both opens and reads directories concurrently.
- thread pool sizes are configurable. cosr:5 would give you 5 threads.
- see the docs for more info
