drbd_csum_bio() in drbd_sender.c uses a constant (REQ_OP_WRITE_SAME) that was removed from the kernel in February: - https://github.com/LINBIT/drbd/blob/drbd-9.1/drbd/drbd_sender.c#L360-L361
Here's where the constant was removed: - https://github.com/torvalds/linux/commit/73bd66d9#diff-3b0e31d21eab4c9595b9d14730e06067f27b9f21134edcd9cb47215d23d69583 I'm using CentOS Stream 9 with kernel-5.14.0-130.el9.x86_64. I'm aware that CentOS Stream "is not one of the distributions we care about too deeply." I'm not sure to what extent we care about it though. It would be nice to be able to build from the latest drbd upstream using a recent kernel. Please let me know if this is something we can get fixed. -- Regards, Reid Wahl (He/Him) Senior Software Engineer, Red Hat RHEL High Availability - Pacemaker _______________________________________________ Star us on GITHUB: https://github.com/LINBIT drbd-user mailing list drbd-user@lists.linbit.com https://lists.linbit.com/mailman/listinfo/drbd-user
