Hi, I managed to extract the usable shadow mbr size out of my 850Evos OPAL_TABLE_TABLE and added an appropriate check into the write function. As this involves more than just a few lines, I decided to split the v2 of this subpatch into 4 separate patches. I am unsure what whould be the best practice for such an situation but hope it is okay like this. Also the userspace exported pointer is replaced with an u64 value.
