Is it the same issue? Jetbrains ide stopped working after updating to 6.8: |

Looks like it. |

I've just run up against this while trying 24.04 (noble) devel, and trying to setup Root on ZFS. 24.04 is to be released next month some time, and currently it's including zfs-2.2.2 with kernel 6.8. Specifically,
Quick strace shows it is indeed Bit of a pain, any dpkg script that runs systemd-sysusers ends up failing and leaves the package in a broken state :( |

You should probably report that to Ubuntu then. |

Linux 6.8 removes generic_copy_file_range(), which had been reduced to a simple wrapper around splice_copy_file_range(). Detect that function directly and use it if generic_ is not available.

System information
Describe the problem you're observing
I'm getting a copy_file_range error when copying text files, but not binary files using a ruby command which uses
copy_file_range.I've opened an issue ruby/fileutils#118 , but this might be a zfs issue, as kernel changes ought not to affect userspace.
Describe how to reproduce the problem
This occurs in a docker container. Example container inside which I can reproduce this error, running on an x86_64 host on a 6.8-rc5 kernel and OpenZFS 2.2.3:
Example commands inside that container that cause the issue:
This problem goes away if I boot into Kernel 6.7.5
Include any warning/errors/backtraces from the system logs
There are no other logs that show this issue... it doesn't occur if I copy a non-text-file.
