Hey all, util-linux v2.39-rc1 coming to rawhide, Release Notes: https://kernel.org/pub/linux/utils/util-linux/v2.39/v2.39-ReleaseNotes I usually don't report util-linux Fedora updates, but this one is special. This new version provides libmount with support for new kernel mount API (syscalls fsconfig, fsmount, open_tree, etc.). Some kernel parts may not be fully ported to the new API. Unfortunately, the reliable way to detect possible issues is to test all less usual use cases and mount options combinations in the real distribution. For example, a well-known issue is btrfs when mixed with selinux mount options. In this case, libmount falls back to the classic mount(2) syscall. We need to gather all such cases. If you see any unexpected behavior, please report it to https://github.com/util-linux/util-linux/issues, the ideal report is with libmount debug output (LIBMOUNT_DEBUG=all mount /foo ...). Thanks!
