parentlib/test_scanf: split up number parsing test routines (diff)
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. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
