      NFS: dprintk() should not print negative fileids and inode numbers · 1e8968c5
      Niels de Vos authored
      A fileid in NFS is a uint64. There are some occurrences where dprintk()
      outputs a signed fileid. This leads to confusion and more difficult to
      read debugging (negative fileids matching positive inode numbers).

      nfs: fix dead code of ipv6_addr_scope · a8c22754
      Alexander Aring authored
      The correct way to check on IPV6_ADDR_SCOPE_LINKLOCAL is to check with
      the ipv6_addr_src_scope function.
      
      Currently this can't be work, because ipv6_addr_scope returns a int with
      a mask of IPV6_ADDR_SCOPE_MASK (0x00f0U) and IPV6_ADDR_SCOPE_LINKLOCAL
      is 0x02. So the condition is always false.

      sunrpc: Fix infinite loop in RPC state machine · 6ff33b7d
      Weston Andros Adamson authored
      When a task enters call_refreshresult with status 0 from call_refresh and
      !rpcauth_uptodatecred(task) it enters call_refresh again with no rate-limiting
      or max number of retries.
      
      Instead of trying forever, make use of the retry path that other errors use.
      
      This only seems to be possible when the crrefresh callback is gss_refresh_null,
      which only happens when destroying the context.
      
      To reproduce:
      
      1) mount with sec=krb5 (or sec=sys with krb5 negotiated for non FSID specific
         operations).
      
      2) reboot - the client will be stuck and will need to be hard rebooted

      tracing: Only run synchronize_sched() at instance deletion time · 3ccb0123
      Steven Rostedt authored
      It has been reported that boot up with FTRACE_SELFTEST enabled can take a
      very long time. There can be stalls of over a minute.
      
      This was tracked down to the synchronize_sched() called when a system call
      event is disabled. As the self tests enable and disable thousands of events,
      this makes the synchronize_sched() get called thousands of times.
      
      The synchornize_sched() was added with d562aff9 "tracing: Add support
      for SOFT_DISABLE to syscall events" which caused this regression (added
      in 3.13-rc1).
      
      The synchronize_sched() is to protect against the events being accessed
      when a tracer instance is being deleted. When an instance is being deleted
      all the events associated to it are unregistered. The synchronize_sched()
      makes sure that no more users are running when it finishes.
      
      Instead of calling synchronize_sched() for all syscall events, we only
      need to call it once, after the events are unregistered and before the
      instance is deleted. The event_mutex is held during this action to
      prevent new users from enabling events.
