[PATCH] f2fs: super: constify fscrypt_operations structure

Show all headers | View raw

Declare fscrypt_operations structure as const as it is only stored in
the s_cop field of a super_block structure. This field is of type const,
so fscrypt_operations structure having this property can be made const
too.
