5.10-stable review patch. If anyone has any objections, please let me know. ------------------ From: Alexander Egorenkov <egorenar@xxxxxxxxxxxxx> [ Upstream commit 7faacaeaf6ce12fae78751de5ad869d8f1e1cd7a ] Initialize the correct fields of the nvme dump block. This bug had not been detected before because first, the fcp and nvme fields of struct ipl_parameter_block are part of the same union and, therefore, overlap in memory and second, they are identical in structure and size.
