Yes, this is a Toshiba card. I've sent the patch as a reply to Linus' email.

Very interesting. So the manfid is the same as on most Kingston cards,
but the oemid is different. Most cards have a two-letter ASCII code
in there, 0x544d ("TM") on Kingston cards, and I always assumed that
this stood for "Toshiba Memory".

What is even stranger is the size value (among other fields) in the CSD,
the card claims a size of exactly 32GB, which I find hard to believe,
given that there are always some bad and reserved blocks.

Are you sure that the card you have is authentic? I've heard a lot about
fake USB sticks advertising a size that is much larger than the actual
flash inside of them.

Also this is the first card that I see advertise an allocation unit
size of 2MB (preferred_erase_size), all other cards seem to advertise
4 MB these days, even if they actually have 2 or 8 MB.

This is a Toshiba eMMC part. It is 32GB as far as the OS can see and access.
