Commit ab909585 ("staging: lustre: Cleanup variable declarations in mdc_enqueue()") broke Lustre flock handling introducing access to uninitialized req variable, leading to bizzare crash in a later call to __req_capsule_offset with invalid pill value. Set req to NULL just for this case as in all other cases req is explicitly initialized with request packing call. Signed-off-by:

When a group lock with GID=0 is released (put_grouplock is called), an assertion in cl_put_grouplock is hit. We should not allow group lock requests with GID=0, instead we should return -EINVAL. Signed-off-by:

Since reg->kr_fp can be changed inside the foreach loop, kkuc_groups must be write protected, and not just read protected. This should fix the following oops, which could happen if two different threads simultaneously execute the function, and EPIPE is returned.

It is possible that when fld client is trying to lookup seq on one of MDT, but the connection between the client and the MDT is not being initialized yet, especially during striped dir creation, because client will only send create req to the master MDT, then master MDT will distribute the operation to all of other MDT, instead of client distributing these requests, which will usually trigger the connection. In this case, we will send the fld request to MDT0, since it has all of location information. Signed-off-by:

In vvp_io_read_lock(), it used to decide if to add read lock by checking lli_has_smd. Accessing lli_has_smd is racy when an empty file is turned into raid0, therefore, it may result in read requests are issued without corresponding lock. Signed-off-by:

When the time of LRU resizing exceeds waiting period of recalculation, the ldlm daemon will keep on resizing without any interval of rest. That will cause high CPU load. This patch fixes the problem by setting the recalculation timestamp after LRU resizing finishes rather than before it. What is more, an interval of one second is enforced between each recalculation.

ptlrpcd_check() always scan all requests on ptlrpc_request_set and try to finish completed requests, this is low efficiency. Even worse, l_wait_event() always checks condition for twice before sleeping and one more time after waking up, which means it will call ptlrpcd_check() for three times in each loop. This patch will move completed requests at the head of list in ptlrpc_check_set(), with this change ptlrpcd_check doesn't need to scan all requests anymore. Signed-off-by:

This function is an awkward helper for nbu2ss_drv_ep_init(). Most of its logic is devoted to determining if the current endpoint is ep0, something the caller can easily do in a single line. And there is not a lot going on beyond that. Move this logic up into nbu2ss_drv_ep_init(). The result is much easier to understand and the resulting function is still viewable within a single screen.
