yield was used to wait until all references of the internal control structure in use are dropped before it is freed. This patch implements padata_flush_queues which actively flushes the padata percpu queues in this case.

padata_get_next needs to check whether the next object that need serialization must be parallel processed by the local cpu. This check was wrong implemented and returned always true, so the try_again loop in padata_reorder was never taken. This can lead to object leaks in some rare cases due to a race that appears with the trylock in padata_reorder. The try_again loop was not a good idea after all, because a cpu could take that loop frequently, so we handle this with a timer instead. This patch adds a timer to handle the race that appears with the trylock. If cpu1 queues an object to the reorder queue while cpu2 holds the pd->lock but left the while loop in padata_reorder already, cpu2 can't care for this object and cpu1 exits because it can't get the lock. Usually the next cpu that takes the lock cares for this object too. We need the timer just if this object was the last one that arrives to the reorder queues. The timer function sends it out in this case. Signed-off-by: Steffen Klassert <steffen.klassert@secunet.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

We don't check "frontend" consistently in crypto_init_spawn2(). We check it at the start of the function but then we dereference it unconditionally in the parameter list when we call crypto_init_spawn(). I looked at the places that call crypto_init_spawn2() and "frontend" is always a valid pointer so I removed the check for null.

H Hartley Sweeten authored
According to the header file, dt3155_io.h, the 50/60 Hz configuration is controlled by a bit in the I2C CSR2 register (bit 2). The function dt3155_init_isr actually reads the I2C CONFIG register into the global I2C_CSR union variable then modifies the bit. It then does a write to the I2C CONFIG register with the global I2C_CONFIG union variable which is not even set with a value anywhere in the driver. My guess is 50Hz operation doesn't even work as-is. Fix this by actually reading and writing the correct register with the correct value.

When detaching a port from the client side (usbip --detach 0), the event thread, on the server side, is going to deadlock. The "eh" server thread is getting USBIP_EH_RESET event and calls: -> stub_device_reset() -> usb_reset_device() the USB framework is then calling back _in the same "eh" thread_ : -> stub_disconnect() -> usbip_stop_eh() -> wait_for_completion() the "eh" thread is being asleep forever, waiting for its own completion. This patch checks if "eh" is the current thread, in usbip_stop_eh(). Signed-off-by: Eric Lescouet <eric@lescouet.org> Cc: stable <stable@kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

This patch makes the HyperV network device use the same naming scheme as other virtual drivers (Xen, KVM). In an ideal world, userspace tools would not care what the name is, but some users and applications do care. Vyatta CLI is one of the tools that does depend on what the name is.

The word oops comes to mind. Original patch to merge the two work queues in here (prior to Greg taking them into staging) changed the top half to only use one of them and the bottom half to assume it was the other. Currently causes a NULL pointer dereference if you enable any of the events on an lis3l02dq. Just goes to show I need a few more regression tests.

A while ago I provided a patch that fixed device detection after device removal (USB: sl811-hcd: Fix device disconnect). Chris Brissette pointed out that the detection/removal counter method to distinguish insert or remove my fail under certain conditions. Latest SL811HS datasheet (Document 38-08008 Rev. *D) indicates that bit 6 (SL11H_INTMASK_RD) of the Interrupt Status Register together with bit 5 (SL11H_INTMASK_INSRMV) can be used to determine whether a device has been inserted or removed.
