From 52b01a808696836d5d3382cd4ec6816e65f2ecc5 Mon Sep 17 00:00:00 2001 From: Daniel Rosenberg Date: Thu, 3 Jun 2021 09:50:37 +0000 Subject: [PATCH] f2fs: Show casefolding support only when supported commit 39307f8ee3539478c28e71b4909b5b028cce14b1 upstream. The casefolding feature is only supported when CONFIG_UNICODE is set. This modifies the feature list f2fs presents under sysfs accordingly.
