2016-03-12iio: core: implement iio_device_{claim|release}_direct_mode()Alison Schofield2-0/+41
It is often the case that the driver wants to be sure a device stays in direct mode while it is executing a task or series of tasks. To accomplish this today, the driver performs this sequence: 1) take the device state lock, 2) verify it is not in a buffered mode, 3) execute some tasks, and 4) release that lock. This patch introduces a pair of helper functions that simplify these steps and make it more semantically expressive. iio_device_claim_direct_mode() If the device is not in any buffered mode it is guaranteed to stay that way until iio_release_direct_mode() is called. iio_device_release_direct_mode() Release the claim. Device is no longer guaranteed to stay in direct mode. Signed-off-by: Alison Schofield <[email protected]> Signed-off-by: Jonathan Cameron <[email protected]>

This adds support for Freescale's (now NXP's) FXLS8471Q accelerometer. We use MMA8451Q's configuration because for what the driver supports, FXLS8471Q is the same. Support for FXLS8471Q's features (fast SPI interface and a larger FIFO, among others) can be added to this driver anytime.

2016-03-05iio: mma8452: avoid switching to active because of config changeMartin Kepplinger1-6/+29
The devices' config registers can only be changed in standby mode. Up until now the driver just held the device *always* active, so for changing a config it was *always* necessary to switch to standby. For upcoming support for runtime pm, the device can as well be in standby mode. Instead of putting runtime pm functions in there, just keep the device in standby if it already is.

2016-03-02staging: lustre: avoid intensive reconnecting for ko2iblndLiang Zhen3-116/+258
When there is a connection race between two nodes and one side of the connection is rejected by the other side. o2iblnd will reconnect immediately, this is going to generate a lot of trashes if: - race winner is slow and can't send out connecting request in short time. - remote side leaves a cmid in TIMEWAIT state, which will reject future connection requests To resolve this problem, this patch changed the reconnection behave: reconnection is submitted by connd only if a zombie connection is being destroyed and there is a pending reconnection request for the corresponding peer. Also, after a few rejections, reconnection will have a time interval between each attempt.

2016-03-02staging: lustre: Change connect peer failed cleanup orderDoug Oucharek1-0/+2
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 connection refcount taken by cmid. It means the connection could be destroyed before kiblnd_connreq_done() finish operations on it.
