           Summary: bdflush(2) is obsolete
           Product: Documentation
           Version: unspecified
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: man-pages
        AssignedTo: documentation_man-pages-ztI5WcYan/vQLgFONoPN62D2FQJk+8+b@public.gmane.org
        ReportedBy: kmoriwak-H+wXaHxf7aLQT0dZR+AlfA@public.gmane.org
        Regression: No


In recent kernel, bdflush(2) syscall is deprecated and not effective to
anything.

Adding some statement about this situation to DESCRIPTION or NOTES section will
be helpful for readers.

I think affected pages are: bdflush(2) and syscalls(2)

Best Regards,

The bdflush(2) man page has long carried this text:

       Note:  Since Linux 2.6, this system call is deprecated and does
       nothing.  It is likely to disappear altogether in a future ker‐
       nel release.  Nowadays, the task performed by bdflush() is han‐
       dled by the kernel pdflush thread.

As far as I can see, the system call still exists, at least for x86-32.

If something further has changed (which exact recent kernel version, and,
ideally a commit ID), please add this info to this bug.
