This patch chain changes the logging implementation to use string_stream
so that the log will grow dynamically.
The first 8 patches add test code for string_stream, and make some
changes to string_stream needed to be able to use it for the log.
The final patch adds a performance report of string_stream.
CHANGES SINCE V5:
Patch 2:
- Avoid cast warning when using KUNIT_EXPECT_EQ() on a gfp_t. Instead pass
the result of the comparison to KUNIT_EXPECT_TRUE(). While it would be
nice to use KUNIT_EXPECT_EQ(), it's probably better to avoid introducing
build or sparse warnings.
- In string_stream_append_test() rename original_content to
stream1_content_before_append.
Patch 7:
- Make string_stream_clear() public (in v5 this was done in patch #8).
- In string-stream-test.c add a wrapper for kfree() to prevent a cast
warning when calling kunit_add_action().
Patch 8:
- Fix memory leak when calling the redirected string_stream_destroy_stub().
Patch 9:
- In kunit-test.c: add wrapper function around kfree() to prevent cast
warning when calling kunit_add_action().
- Fix unused variable warning in kunit_log_test() when built as a module.
