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

Hello,

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

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 :)

"update" is not a program, but a kernel daemon that was superseded by pdflush in 2.5 kernels.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this syscall is obsolete.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
