Description Kazuo Moriwaka 2012-05-16 06:37:23 UTC

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.
