From e6e21970baff4845de74584e2efc8c964a55d574 Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Wed, 2 Jan 2008 16:27:16 -0500 Subject: [PATCH] NFSv4: Fix open_to_lock_owner sequenceid allocation... NFSv4 file locking is currently completely broken since it doesn't respect the OPEN sequencing when it is given an unconfirmed lock_owner and needs to do an open_to_lock_owner. Worse: it breaks the sunrpc rules by doing a GFP_KERNEL allocation inside an rpciod callback. Fix is to preallocate the open seqid structure in nfs4_alloc_lockdata if we see that the lock_owner is unconfirmed. Then, in nfs4_lock_prepare() we wait for either the open_seqid, if the lock_owner is still unconfirmed, or else fall back to waiting on the standard lock_seqid.
