A race condition has been found where connd is cleaning up failed
connections, the peer ref counter goes to zero, but we stil have
a connecting counter > 0.
One possible race is when we are retrying a connection by
calling kiblnd_connect_peer() which itself fails and decrements
the peer ref counter and gets swapped out before it can decrement
the connecting counter. connd swaps in and cleans up the
connection where it sees a peer ref counter of 1 and a connecting
counter of 1. This will trigger the assert seen in LU-7210 when
it decrements the peer counter.
The solution: be sure to decrement the connecting counter
before decrementing the peer counter in the peer connect
failure path.

refcount taken by cmid is not reliable after kiblnd_connreq_done
released the glock because this connection is visible to other
threads, another thread can find and close this connection right
after kiblnd_connreq_done released the glock, if kiblnd_cm_callback
for RDMA_CM_EVENT_DISCONNECTED is called, it can release the

destroyed before kiblnd_connreq_done() finish operations on it.

On some customers' systems, the kernel was compiled with HZ defined
to 100, instead of 1000. This improves performance for HPC applications.
However, to use these systems with Lustre, customers have to re-build
Lustre for the kernel because Lustre directly uses the defined constant
HZ.
Since kernel 2.6.21, some non-HZ dependent timing APIs become non-
inline functions, which can be used in Lustre codes to replace the
direct HZ access.
These kernel APIs include:
jiffies_to_msecs()
jiffies_to_usecs()
jiffies_to_timespec()
msecs_to_jiffies()
usecs_to_jiffies()
timespec_to_jiffies()
And here are some samples of the replacement:
HZ -> msecs_to_jiffies(MSEC_PER_SEC)
n * HZ -> msecs_to_jiffies(n * MSEC_PER_SEC)
HZ / n -> msecs_to_jiffies(MSEC_PER_SEC / n)
n / HZ -> jiffies_to_msecs(n) / MSEC_PER_SEC
n / HZ * 1000 -> jiffies_to_msecs(n)
This patch replaces the direct HZ access in lnet module.

In lnet_ptl_match_delay() we check msg->msg_rx_delayed to see whether
the message has been added to the delay queue. But this check is done
after lnet_ptl_unlock() and lnet_res_unlock(), and the message can be
processed and freed before the check.
Replace the check with checking rc against LNET_MATCHMD_NONE, which
is how the callers of lnet_ptl_match_delay() know whether the message
was added to the delay queue. To make this work we reset rc in the
loop when there was no match and the message hasn't been delayed. In
addition reorganize the code and add comments to clarify the logic.
In lnet_ptl_match_md() a similar msg->msg_rx_delayed is replaced for
the same reason.

Since the # of hops is not a mandatory parameter the LU-6060
patch will cause problems to already existing systems since it
changes the behavior by which a route is determined down.
To fix this case the # of hops now defaults to LNET_UNDEFINED_HOPS
if no hop count is specified.
LNET_UNDEFINED_HOPS is defined to ((__u32)-1). When it's printed as
%d, it displays as -1.
__u32 is used through out the call stack for hop count to explicitly
define the size of the hop count and to avoid any sizing issues when
passing data to and from the kernel.
To keep existing behavior both lnet_compare_routes() and LNetDist()
will treat undefined hop count as hop count 1.
When executing the logic in lnet_parse_rc_info() there is no
longer an assumption that the default hop count is 1. If
the hop count is 1 then it must've been explicitly set by
the user.
