"long unsigned int" : "long unsigned int") To match this, __kernel_size_t is always set to "long unsigned int". But while __kernel_ssize_t is "long" on 64-bit s390x, it is "int" on 32-bit s390, causing compiler warnings like: fs/quota/quota_tree.c:372:4: warning: format '%zd' expects argument of type 'signed size_t', but argument 4 has type 'ssize_t' [-Wformat] To fix this, __kernel_ssize_t should be "long", irrespective of word size.
