Hello,

When switching from 2.4.20 to 2.5.x (x being recent), I have this
message...

What does this mean ?
1 - I have no process named update running,
2 - I can't find anything name update in /etc/rc.d/* recursively.

Regards,
Paul

from fs/buffer.c:
/*
  * There are no bdflush tunables left.  But distributions are
  * still running obsolete flush daemons, so we terminate them here.
  *
  * Use of bdflush() is deprecated and will be removed in a future 
kernel.
  * The `pdflush' kernel threads fully replace bdflush daemons and this 
call.
  */

I'd upgrade whatever package update comes from. I can't seem to find 
that binary around on some of my systems, what distribution and version 
are you running? Maybe it's time to upgrade.

Someone else might know specifics :)

If you have a line with 'update' or 'bdflush' in /etc/inittab,
remove it. (Its obsolete since mid-2.2 or so.)

Nice guess ! I have 
ud:once:/sbin/update 
within inittab.

The puzzling part is that, if it obsolete since mid-2.2, why is it
present on a RedHat 8.0 install ?

However, this question is not important ;-)

Thanks for the info, I'm gonna clean this !

Regards,
Paul

"update" is not a program, but a kernel daemon that was superseded by
pdflush in 2.5 kernels. I just can't remember right know what caused
that warning, but it's similar to the SO_BSDCOMPAT warning that is
triggered when running bind.

calling syscall bdflush() triggers this warning.
this syscall is obsolete.
Things can now be done through /proc/sys/vm
