返回类型：void

参数：

类型参数名称
struct kunit_try_catch *try_catch
void *context
58  Lockdep needs to run a non-constant initializer for on-stack* completions - so we use the _ONSTACK() variant for those that* are on the kernel stack:(try_completion)
59  test等于private: internal use only.
63  context等于context
64  try_completion等于try_completion
65  try_result等于0
66  task_struct等于kthread_run - create and wake a thread.*@threadfn: the function to run until signal_pending(current).*@data: data ptr for @threadfn.*@namefmt: printf-style name for the thread.* Description: Convenient wrapper for kthread_create() followed by(kunit_generic_run_threadfn_adapter, try_catch, "kunit_try_catch_thread")
69  如果是错误则
70  catch(context)
71  返回
74  time_remaining等于wait_for_completion_timeout( & try_completion, kunit_test_timeout())
76  如果time_remaining恒等于0则
77  kunit_err() - Prints an ERROR level message associated with @test.*@test: The test context object.*@fmt: A printk() style format string.* Prints an error level message.(test, "try timed out\n")
78  try_result等于负ETIMEDOUT
81  exit_code等于try_result
83  如果非exit_code则返回
86  如果exit_code恒等于负EFAULT则try_result等于0
88  否则如果exit_code恒等于负EINTR则kunit_err() - Prints an ERROR level message associated with @test.*@test: The test context object.*@fmt: A printk() style format string.* Prints an error level message.(test, "wake_up_process() was never called\n")
90  否则如果exit_code则kunit_err() - Prints an ERROR level message associated with @test.*@test: The test context object.*@fmt: A printk() style format string.* Prints an error level message.(test, "Unknown error: %d\n", exit_code)
