Subject: [PATCH] net: correct off-by-one write allocations reports

From: Eric Dumazet <[email-masked]>
Date: Wed, 17 Jun 2009 08:41:53 +0200

David

Please find the followup patch I promised yesterday.

Some review still needed for net/atm, since this protocol
sets sock_wmem_alloc initial value to 0

Thank you

[PATCH] net: correct off-by-one write allocations reports

commit 2b85a34e911bf483c27cfdd124aeb1605145dc80 
(net: No more expensive sock_hold()/sock_put() on each tx)
changed initial sk_wmem_alloc value.

We need to take into account this offset when reporting
sk_wmem_alloc to user, in PROC_FS files or various
ioctls (SIOCOUTQ/TIOCOUTQ)
