 for simple situations.  Files containing a single integer value can be

+    struct dentry *debugfs_create_u8(const char *name, umode_t mode,

+    struct dentry *debugfs_create_u64(const char *name, umode_t mode,

 These files support both reading and writing the given value; if a specific
 file should not be written to, simply set the mode bits accordingly.  The
 values in these files are in decimal; if hexadecimal is more appropriate,
 the following functions can be used instead:
 
-    struct dentry *debugfs_create_x8(const char *name, mode_t mode,

+    struct dentry *debugfs_create_x64(const char *name, umode_t mode,
 				      struct dentry *parent, u64 *value);
 
 These functions are useful as long as the developer knows the size of the
 value to be exported.  Some types can have different widths on different
 architectures, though, complicating the situation somewhat.  There is a
 function meant to help out in one special case:
 
-    struct dentry *debugfs_create_size_t(const char *name, mode_t mode,
