[PATCH][next] bcachefs: Replace zero-length arrays with flexible-array members

From: Gustavo A. R. Silva
Date: Tue Nov 28 2023 - 13:23:02 EST


Fake flexible arrays (zero-length and one-element arrays) are
deprecated, and should be replaced by flexible-array members.

So, replace zero-length arrays with flexible-array members
in multiple structures.
