I'd recommend using static const char arrays.

Do you need to validate the length of the string here?

You need to annotate the function with an __acquires() to indicate that it
returns with a lock held for Sparse checking. I think you should be able to
do:
__acquires(tkey->sem)
on the line before the '{'.

Ditto.

I think I'd call it alloc_sdesc() rather than init_sdesc().

size_t not 'const unsigned int' please. There are multiple of these within
the patch.

Superfluous cast.
