+Subject: [PATCH] mkfs/fsck: use PRIu64/PRIx64 to print 64-bit types
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Change cpu_to_le64()/cpu_to_le32()/cpu_to_le16() defines to
+return determined types (instead of __le64/__le32/__le16) and
+use PRIu64/PRIx64 to print 64-bit types.
+
+Fixes:
+
+ mkfs.c:60:14: error: format ‘%llu’ expects argument of type ‘long long unsigned int’, but argument 2 has type ‘long unsigned int’ [-Werror=format=]
+ exfat_debug("Volume Length(sectors) : %llu\n",
