Subject: rxrpc: Record calls that need to be accepted
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=e6f3afb3fc058e17b407b6f7cac08058b19e641c;p=linux-beck.git

rxrpc: Record calls that need to be accepted

Record calls that need to be accepted using sk_acceptq_added() otherwise
the backlog counter goes negative because sk_acceptq_removed() is called.
This causes the preallocator to malfunction.

Calls that are preaccepted by AFS within the kernel aren't affected by
this.
