lib/test_vmalloc: add no_block_alloc_test case
Patch series "__vmalloc()/kvmalloc() and no-block support", v4.
This patch (of 10):
Introduce a new test case "no_block_alloc_test" that verifies non-blocking
allocations using __vmalloc() with GFP_ATOMIC and GFP_NOWAIT flags.
It is recommended to build kernel with CONFIG_DEBUG_ATOMIC_SLEEP enabled
to help catch "sleeping while atomic" issues. This test ensures that
memory allocation logic under atomic constraints does not inadvertently
sleep.
