This series originates from [1] which addresses feedback [2].
Sending this as v5 since [1] was posted as v4...
Briefly, here is what the series covers:
Patch 1 groups conring code together to better maintainability.
There were conring bits all over the place in console.c.
Patch 2 introduces CONRING_CONRING_SHIFT to select compile-time
conring buffer size.
Patch 3 updates conring{,_size} annotations to __ro_after_init as per [2].
Patch 4 optimizes switch from early conring to permanent conring.
Patches 5-6 update the conring buffer allocation code and add some
verbose logging around buffer size selection.
