Hi All,
In our product system, we have several sata disks attached to one
machine. So when one of the disk fails, the jbd2(yes, we use ext4) will
hang forever and we will get something in /var/log/messages like below.
It seems to me that the io sent to the scsi layer is never returned back

All callers of throtl_update_dispatch_stats uses tg_to_blkg and then
in this function we use blkg_to_tg again to change it back. So remove
all these useless conversion and use throtl_grp directly to call
throtl_update_dispatch_stats.

Currently, if the IO is throttled by io-throttle, the SA has no idea of
the situation and can't report it to the real application user about
that he/she has to do something. So this patch adds a new interface
named blkio.throttle.io_queued which indicates how many IOs are

Hi Stephen,
Thanks for the report.
the corresponding fix is already sent to Ted in the patch named "ext4:
Fix inline data build warning found by kernel build testing.", but it
seems that Ted hasn't pushed it into ext4dev yet.
Thanks
Tao

'start' is set to buf + buflen and do the '--' immediately.
Just set it to 'buf + buflen - 1' directly.

When we are using netpoll, we don't go through the normal
transmit process. In this case, bond_select_queue is not called
and qdisc_skb_cb(skb)->slave_dev_queue_mapping isn't set.
So when netpoll_send_skb_on_dev calls ndo_start_xmit and we
enter bond_dev_queue_xmit, we
