The source listing is preceded by a cross-reference listing every defined
constant, struct, global variable, and function in xv6. Each entry gives,
on the same line as the name, the line number (or, in a few cases, numbers)
where the name is defined. Successive lines in an entry list the line
numbers where the name is used. For example, this entry:
namei 4760
0333 4760 4859 4908
4958 5007 5016 5414
5427 5512 5560 5640
indicates that namei is defined on line 4760 and is mentioned on twelve lines
on sheets 03, 47, 48, 49, 50, 54, 55, and 56.
The numbers to the left of the file names in the table are sheet numbers.
The source code has been printed in a double column format with fifty
lines per column, giving one hundred lines per sheet (or page).
Thus there is a convenient relationship between line numbers and sheet numbers.
