From af494af38580a35b92f921639a60630a2307bcc2 Mon Sep 17 00:00:00 2001 From: Eric Biggers Date: Mon, 14 Aug 2023 11:29:03 -0700 Subject: libfs: remove redundant checks of s_encoding Now that neither ext4 nor f2fs allows inodes with the casefold flag to be instantiated when unsupported, it's unnecessary to repeatedly check for support later on during random filesystem operations.
