All,

I was just reading the kernel newbies page about the new features in 2.6.19: http://kernelnewbies.org/Linux_2_6_19

But I know, because I rebuilt my kernel (for the fun of it, and to check out a problem I had), and needed certain patches like for apparmor, etc., that the 10.1 kernel had this patch. I found out when I mounted a USB drive with my self built kernel, when I found the patch and added it to mine, so I would be fairly certain it is already in 10.2, and

And saw: == FAT: Add "-o flush" mount option for fat for removable media devices (USB flash-based memory devices, MP3 players). Mounting with -o flush tells FAT to write things to disk as quickly as possible. It is like -o sync, but much faster (and not as safe). Think of it like a fast "async" mount (commit) ==

Does anyone know if this is in the SUSE 10.2 kernel?

And if so, if the SUSE automount logic is using this flag instead of -o sync like 10.1 does?

This feature, while nice, will not go to openSUSE 10.2, because it is feature-frozen, and release is near.

It may get included in 10.3 however. --

Thanks, thats what I suspected, but sometimes SUSE backports new features into older kernels, so I was hopeful. I am running 10.2, and the patch is in the kernel. I just checked, and

-o flush works here, and looking at the changelogs for 10.1 it appears it was added then. My USB devices appear to be mounted with it automatically. The kde and gnome automount things have support too. See http://benjiweber.co.uk/screenshots/usb-opts.png the Flushed IO option.

I'm not sure what the difference between this and what is mentioned in the 2.6.19 changelog. Perhaps someone could enlighten me.

Interesting. It had not occurred to me to check 10.1, but at least one of my 10.1 machines is using the flush option as well. Obviously the good folks at Novell have backported this patch and added it to their 2.6.18 kernel. I must say that as many threads as there are on here about USB thumbdrives and hot-plugging I'm amazed not to have read about this before.

No - we developed it ourselves and forward ported it and finally got it merged into 2.6.19,

Which is an interesting example of the sort of concrete development that the Novell/SUSE team are putting into Linux.
