[PATCH v5 00/10] kunit: Add dynamically-extending log

From: Richard Fitzgerald
Date: Thu Aug 24 2023 - 10:33:17 EST


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 V4:
- Re-ordered the first 3 patches from V4 to squash the first two sets
of string_stream tests into a single patch.
- Changed is_literal() so it doesn't need a struct kunit.
- Split out the new resource-managed alloc and free functions into
a pre-patch to reduce the amount of code churn when the string_stream
is decoupled from kunit.
- Wrapped the call to string_stream_geT_string() in string-stream-test
in a local function to reduce the amount of code churn when the
string_stream is decoupled from kunit.
- Some minor changes to test implementations.
- string_stream is now completely separated from kunit and the 'test'
member of struct string_stream has been eliminated.
