[PATCH 1/2] f2fs: Show casefolding support only when supported

From: Daniel Rosenberg
Date: Wed Jun 02 2021 - 00:16:07 EST


The casefolding feature is only supported when CONFIG_UNICODE is set.
This modifies the feature list f2fs presents under sysfs accordingly.

Fixes: 5aba54302a46 ("f2fs: include charset encoding information in the superblock")
