Fedora 39 with 6.10.11-100.fc39 kernel dereferences NULL in
raid10_size and locks up with 3-drive raid10 configuration upon its
degradation and reattachment.
How to reproduce:
1. Get 3 USB flash drives
2. mdadm --create -b internal -l 10 -n 3 -z 1G /dev/md0 /dev/sda
/dev/sdb /dev/sdc
3. Unplug 2 USB drives
4. Plug one of the drive again
Happens every time, every USB flash reattachment.
Reproduced on 6.11.2-250.vanilla.fc39.x86_64
Can you use addr2line or gdb to see which codeline is this?
