trapexit/mergerfs 2.38.0 on GitHub

Change Summary

Improvement: Rework how threadpools queue depth. There was a rare bug that affected 1 user that lead to the pool believing there were no queue slots open when there should have been.
Improvement: Better compatibility with older versions of MUSL.
Improvement: Print warnings to stderr and syslog if run as non-root indicating mergerfs may not work correctly.
Improvement: Change how allow_other auto-setting works. Only set if running as root for those users who are on shared hosts with user_allow_other disabled and all activity is done as their user id. There may still be edge cases that fail but if it works for them I don't want to disallow it.
Add flushonclose feature. Takes advantage of a newer FUSE feature which gives the server control over if a flush is issued at file close. Defaults to a less aggressive policy of only flushing when a file is opened for write.
