From 74361cb6828398a96167b3234e186fbd731e5f30 Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Mon, 14 Aug 2006 08:54:48 -0700 Subject: [PATCH] [PATCH] fcntl(F_SETSIG) fix fcntl(F_SETSIG) no longer works on leases because lease_release_private_callback() gets called as the lease is copied in order to initialise it. The problem is that lease_alloc() performs an unnecessary initialisation, which sets the lease_manager_ops. Avoid the problem by allocating the target lease structure using locks_alloc_lock().
