First we need a method to tell\nfsnotify_create_event() to use GFP_NOFS and second we need to stop using\none global IN_IGNORED event and allocate them one at a time.  This solves\ncurrent issues with multiple IN_IGNORED on a queue having tail drop\nproblems and simplifies the allocations since we don\u0027t have to worry about\ntwo tasks opperating on the IGNORED event concurrently.\n\nSigned-off-by: Eric Paris \u003ceparis@redhat.com\u003e\n",
