[ Upstream commitf2326fd14a] IMA testing revealed that after an ext4 remount, file accesses triggered full measurements even without modifications, instead of skipping as expected when i_version is unchanged. Debugging showed `SB_I_VERSION` was cleared in reconfigure_super() during remount due to commit1ff2030739("ext4: unconditionally enable the i_version counter") removing the fix from commit960e0ab63b("ext4: fix i_version handling on remount"). To rectify this, `SB_I_VERSION` is always set for `fc->sb_flags` in ext4_init_fs_context(), instead of `sb->s_flags` in __ext4_fill_super(), ensuring it persists across all mounts.
