From 174f930b8e1cad3915819a46bb20da214f68f2b5 Mon Sep 17 00:00:00 2001 From: Kent Overstreet Date: Sat, 29 Apr 2023 13:24:18 -0400 Subject: bcachefs: bkey_ops.min_val_size This adds a new field to bkey_ops for the minimum size of the value, which standardizes that check and also enforces the new rule (previously done somewhat ad-hoc) that we can extend value types by adding new fields on to the end. To make that work we do _not_ initialize min_val_size with sizeof, instead we initialize it to the size of the first version of those values.
