Apache 2.0 is still too strict for some 3rd-party integration.
Let's switch to GPL-2.0+ OR MIT dual license since we're absolutely

From: Gao Xiang @ 2026-04-02 6:09 UTC (permalink / raw)
To: linux-erofs; +Cc: Gao Xiang
Let's switch other source files to MIT license since we're absolutely
NOT working on secret rocket science, so licenses should not be
a bottleneck to innovation in the Cloud Native and AI era.
