[PATCH RFC] stubdom: Change vTPM shared page ABI
Since the vTPM implementations are being incorproated into Xen and
possibly upstream Linux, I would like to see if this protocol change
could be added before we have significant legacy implementations. If
not, I still think it would be useful as either a v2 or negotiated
protocol change.
The current vTPM protocol is a copy of the network protocol. This was
likely done for ease of implementation,

[PATCH 00/10] RFC: move logical block size checking to the block core
This patch series aims to move the logical block size checking to the
block code.
This was inspired by missing check for valid logical block size in
virtio-blk which causes the kernel to crash in a weird way later on
when it is invalid.
I added blk_is_valid_logical_block_size which returns true iff the
block size is one of supported sizes.
I added this check to virtio-blk, and also converted
