The problem is that the garbage collector for the 'host' structures nlm_gc_hosts(), holds nlm_host_mutex while calling down to nlmsvc_mark_resources, which, eventually takes the file->f_mutex. We cannot therefore call nlmsvc_lookup_host() from within nlmsvc_create_block, since the caller will already hold file->f_mutex, so the attempt to grab nlm_host_mutex may deadlock. Fix the problem by calling nlmsvc_lookup_host() outside the file->f_mutex. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> |
