Question on splice

["Saswat Praharaj" <saswat@gmail.com>]

Hello All,

I am a linux application programmer and kernel newbie.

I would like to use splice() / tee() to do some packet forwarding.
I think these two systems calls are there in 2.6.18 kernel.

My company is deciding to use either 2.6.21 or 2.6.22 kernel in our product.

My question is : Is splice() stable in 2.6.21 / 2.6.22 ?

I found this link where it says

 http://lwn.net/Articles/251707/ (search splice)

Jens Axboe (2):
 splice: fix direct splice error handling
 Fix race with shared tag queue maps


Looks like there were some issues with splice that has been fixed in
2.6.22.9 kernel.

I am not sure how critical is that problem . Can I still use the
2.6.21/2.6.22 kernel for splice without any major issues ?
If not, which kernel version would give me a stable splice() .

Please note that I am not subscribed to this list , so please CC me (a
reply-all would do) in your reply.


Thanks in advance.
