      ocfs2: avoid unaligned access to dqc_bitmap · 93925579
      Akinobu Mita authored
      The dqc_bitmap field of struct ocfs2_local_disk_chunk is 32-bit aligned,
      but not 64-bit aligned.  The dqc_bitmap is accessed by ocfs2_set_bit(),
      ocfs2_clear_bit(), ocfs2_test_bit(), or ocfs2_find_next_zero_bit().  These
      are wrapper macros for ext2_*_bit() which need to take an unsigned long
      aligned address (though some architectures are able to handle unaligned
      address correctly)
      
      So some 64bit architectures may not be able to access the dqc_bitmap
      correctly.
      
      This avoids such unaligned access by using another wrapper functions for
      ext2_*_bit().  The code is taken from fs/ext4/mballoc.c which also need to
      handle unaligned bitmap access.

      Btrfs: fix meta data raid-repair merge problem · f4a8e656
      Jan Schmidt authored
      Commit 4a54c8c1 introduced raid-repair, killing the individual
      readpage_io_failed_hook entries from inode.c and disk-io.c. Commit
      4bb31e92 introduced new readahead code, adding a readpage_io_failed_hook to
      disk-io.c.
      
      The raid-repair commit had logic to disable raid-repair, if
      readpage_io_failed_hook is set. Thus, the readahead commit effectively
      disabled raid-repair for meta data.
      
      This commit changes the logic to always attempt raid-repair when needed and
      call the readpage_io_failed_hook in case raid-repair fails. This is much
      more straight forward and should have been like that from the beginning.

      Coinciding with stack trace is the following message:
      
          ib0: ib_address_create failed
      
      The code below in ipoib_mcast_join_finish() will note the above
      failure in the address handle but otherwise continue:
      
                      ah = ipoib_create_ah(dev, priv->pd, &av);
                      if (!ah) {
                              ipoib_warn(priv, "ib_address_create failed\n");
                      } else {
      
      The while loop at the bottom of ipoib_mcast_join_finish() will attempt
      to send queued multicast packets in mcast->pkt_queue and eventually
      end up in ipoib_mcast_send():
      
              if (!mcast->ah) {
                      if (skb_queue_len(&mcast->pkt_queue) < IPOIB_MAX_MCAST_QUEUE)
                              skb_queue_tail(&mcast->pkt_queue, skb);
                      else {
                              ++dev->stats.tx_dropped;
                              dev_kfree_skb_any(skb);
                      }
      
      My read is that the code will requeue the packet and return to the
      ipoib_mcast_join_finish() while loop and the stage is set for the
      "hung" task diagnostic as the while loop never sees a non-NULL ah, and
      will do nothing to resolve.
      
      There are GFP_ATOMIC allocates in the provider routines, so this is
      possible and should be dealt with.
      
      The test that induced the failure is associated with a host SM on the
      same server during a shutdown.
      
      This patch causes ipoib_mcast_join_finish() to exit with an error
      which will flush the queued mcast packets.  Nothing is done to unwind
      the QP attached state so that subsequent sends from above will retry
      the join.
