Pull file table updates from Christian Brauner:
"This annotates struct fdtable's fd array with __counted_by_ptr so
KASAN and the fortified functions can bounds check it against max_fds
and adds a KUnit suite for fdtable. A follow-up uses __struct_size()
in the test since sparse doesn't know __builtin_dynamic_object_size().
FD_PREPARE() is simplified. It was built as an ACQUIRE-style guard on
infrastructure that was never needed. The ACQUIRE machinery and
CLASS_INIT() go away, the variable is declared with __cleanup()
directly, struct fd_prepare loses its err field since the fd either
holds the descriptor or the error, and callers get a const pointer to
the guard behind a UNIQUE_ID() name so they can't shadow it. Code
generation is identical"
