FYI: MX Linux currently is the most downloaded distro on distro watch. I erroneously assumed that there was only ONE Linux kernel bug fix team. My mistake.
So, what is the process where kernel bugs fixed by Ubuntu migrate to the other distro kernels and vice versa? How do I figure out what official bug number fixed my hfs+ bug, as there is no reference to hfs in 5.11 change log?

I have a Mini Mac that I share files via an USB flash drive formatted with hfs+ from the laptops with Ubuntu installed. I had no issues with Ubuntu Mate 18.10. I noticed that very large files, typicality larger than 100 MB, would have read errors or sometimes have a zero file size. One particular file about 500MB fails nearly every time. Other files, down to about 100MB fail sometimes. I bought a new USB flash drive, but have the same failures on that. I have an identical flash drive formatted with ext4 which has no issues. I'm currently booting to Ubuntu Mate 18.10 to write the hfs+ USB flash drive. 1007 ceres ~ cat /proc/version_signature Ubuntu 5.4.0-42.46-generic 5.4.44 1000 ceres ~ lsb_release -rd Description: Ubuntu 20.04.1 LTS Release: 20.04 1005 admin@ceres ~ sudo lspci -vnvn > lspci-vnvn.log pcilib: sysfs_read_vpd: read failed: Input/output error pcilib: sysfs_read_vpd: read failed: Input/output error --- ProblemType: Bug ApportVersion: 2.20.11-0ubuntu27.6 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: uschcld 1581 F.... pulseaudio CasperMD5CheckResult: skip CurrentDesktop: MATE DistroRelease: Ubuntu 20.04 InstallationDate: Installed on 2020-05-17 (91 days ago) InstallationMedia: Ubuntu 20.04 LTS "Focal Fossa" - Release amd64 (20200423) Lsusb: Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 001 Device 004: ID 0408:a030 Quanta Computer, Inc.
