From cd1124244be30fd3e87da9186508aab371e9307d Mon Sep 17 00:00:00 2001 From: Kent Overstreet Date: Sun, 8 Jun 2025 12:35:20 -0400 Subject: [PATCH] bcachefs: Ensure that snapshot creation propagates has_case_insensitive We normally can't create a new directory with the case-insensitive option already set - except when we're creating a snapshot. And if casefolding is enabled filesystem wide, we should still set it even though not strictly required, for consistency.
