[RFC PATCH 0/2] drm: make drm_get_{connector, encoder}_name thread safe

[Jani Nikula <jani.nikula@intel.com>]

Hi all -

This series stores connector/encoder names in the relevant structs to
make the name getters thread safe.

What say you, is the wasted memory too high a price to pay for the
thread safety and implementation simplicity of this approach? I think
making drm_get_connector_name and drm_get_encoder_name return allocated
buffers makes a lot of code really ugly and error prone.

I am assuming connector_type, connector_type_id, encoder_type, and
encoder.base.id remain unchanged for the lifetime of the
connector/encoder - is that a correct assumption?

BR,
Jani.


N.B. I did not actually test this...
