We used to have something in Btrfs to mitigate this called inode_cache, but it was turned into a no-op in 5.11 and the documentation was removed in 5.12: https://github.com/kdave/btrfs-progs/commit/1af37385e258aabc684484aff8e5def442ada9bb If we have a workload example that subvolumes don't work for, then I'm happy to advocate upstream to do something to address the problem more directly. -- 真実はいつも一つ!/ Always, there's only one truth! _______________________________________________ devel mailing list -- devel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to devel-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@xxxxxxxxxxxxxxxxxxxxxxx Do not reply to spam, report it: https://pagure.io/fedora-infrastructure/new_issue
