            Bug ID: 26746
           Summary: mallinfo doc wrongly states that smblks and fsmblks
           Product: glibc
           Version: 2.33
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: libc
          Assignee: unassigned at sourceware dot org
          Reporter: mtk.manpages at gmail dot com
                CC: drepper.fsp at gmail dot com
  Target Milestone: ---

The info doc for mallinfo() (or now mallinfo2()) has long said that the
'smblks' and 'fsmblks' fields are unused. But this is not so, as can be
verified from the source code.
