#     thunderbolt: test: split up test cases in tb_test_credit_alloc_all
#     
#     The tb_test_credit_alloc_all() function had a huge number of
#     KUNIT_ASSERT() statements, all of which (though the magic of many many
#     layers of inscrutable macros) ended up allocating and initializing
#     various test assertion structures on the stack.
#     
#     Don't do that.  The kernel stack isn't infinite, and we have compiler
#     warnings (now errors) for the case where a stack frame grows too large.
#     
#     Like it did here, by not an inconsiderable margin:
#     
#        drivers/thunderbolt/test.c: In function ‘tb_test_credit_alloc_all’:
#        drivers/thunderbolt/test.c:2367:1: error: the frame size of 4500 bytes is larger than 2048 bytes [-Werror=frame-larger-than=]
#         2367 | }
#              | ^
#     
#     Solve this similarly to the lib/test_scanf case: split out the tests
#     into several smaller functions, each just testing one particular tunnel
#     credit allocation.
#     
#     This makes the i386 allyesconfig build work for me again.
