 .Sh DESCRIPTION
 The kernel unit number allocator is a generic facility, which allows to allocate
 unit numbers within a specified range.
-.Bl -ohang
+.Bl -tag -width indent
 .It Fn new_unrhdr low high mutex
 Initialize a new unit number allocator entity.
+The
 .Fa low
 and
 .Fa high
+arguments
 specify minimum and maximum number of unit numbers.
 There is no cost associated with the range of unit numbers, so unless the resource
 really is finite,
-.Va INT_MAX
+.Dv INT_MAX
 can be used.
 If
 .Fa mutex
 is not
-.Va NULL ,
+.Dv NULL ,
 it is used for locking when allocating and freeing units.
-Otherwise internal mutex is used.
+Otherwise, internal mutex is used.
 .It Fn delete_unrhdr uh
 Destroy specified unit number allocator entity.
 .It Fn alloc_unr uh
 Return a new unit number.
 The lowest free number is always allocated.
 This function does not allocate memory and never sleeps, however it may
-block on mutex.
-If no free unit numbers are left
-.Va -1
+block on a mutex.
+If no free unit numbers are left,
+.Li \-1
 is returned.
 .It Fn alloc_unrl uh
 Same as
 .Fn alloc_unr
-except that mutex is assumed to be locked already and thus is not used.
+except that mutex is assumed to be already locked and thus is not used.
 .It Fn free_unr uh
 Free a previously allocated unit number.
 This function may require allocating memory, and thus it can sleep.
