12 path
13 path to report

15 buf
16 buffer to return value in

18 buflen
19 buffer length

22 Convert a dentry into an ASCII path name. If the entry has been deleted
23 the string “ (deleted)” is appended. Note that this is ambiguous.
24
25 Returns a pointer into the buffer or an error code if the path was too
26 long. Note: Callers should use the returned pointer, not the passed in
27 buffer, to use the name! The implementation often starts at an offset
28 into the buffer, and may leave 0 bytes at the start.
29
30 “buflen” should be positive.
