The patch titled
NLM: Fix double free in __nlm_async_call
has been removed from the -mm tree. Its filename was
nlm-fix-double-free-in-__nlm_async_call.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: NLM: Fix double free in __nlm_async_call
From: Trond Myklebust <[EMAIL PROTECTED]>
rpc_call_async() will always call rpc_release_calldata(), so it is an
error for __nlm_async_call() to do so as well.
