Removing a call to the taos_chip_off() makes it unused when CONFIG_PM is disabled: drivers/staging/iio/light/tsl2583.c:438:12: error: ‘taos_chip_off’ defined but not used [-Werror=unused-function] This removes all the #ifdef in this file, and marks the PM functions as __maybe_unused instead, which is more reliable and gives us better compile time coverage.

Otherwise, if the race between page fault and truncate occurs, it will cause the page fault routine to return an EIO error. In filemap_fault() { page_not_uptodate: ... ClearPageError(page); error = mapping->a_ops->readpage(file, page); if (!error) { wait_on_page_locked(page); if (!PageUptodate(page)) error = -EIO; } ... } However, I tend to think this is a defect in kernel implementation, because it assumes PageUptodate shouldn't be cleared but file read routine doesn't make the same assumption.

When stride-RA hit case miss, we only reset normal sequential read-ahead window, but not reset the stride IO to avoid the overhead of re-detecting stride IO. While when the normal RA window is set to not insect with the stride-RA window, when we try to increase the stride-RA window length later, the presumption does not hold. This patch resets the stride IO as well in this case. Signed-off-by:

cpu_pattern can specify exactly 1 cpu in a partition: "0[0]". That means CPT0 will have CPU 0. CPU 0 can have hyperthreading enabled. This combination would result in weight = cfs_cpu_ht_nsiblings(0); hrp->hrp_nthrs = cfs_cpt_weight(ptlrpc_hr.hr_cpt_table, i); hrp->hrp_nthrs /= weight; evaluating to 0. Where cfs_cpt_weight(ptlrpc_hr.hr_cpt_table, i) == 1 weight == 2 Therefore, if hrp_nthrs becomes zero, just set it to 1. Signed-off-by:

PW lock isn't replayed once a lock is marked LDLM_FL_CANCELING and glimpse lock doesn't wait for conflicting locks on the client. So the server will grant a PR lock in response to the glimpse lock request, which conflicts with the PW lock in LDLM_FL_CANCELING state on the client. Lock in LDLM_FL_CANCELING state may still have pending IO, so it should be replayed until LDLM_FL_BL_DONE is set to avoid granted conflicting lock by a server. Seagate-bug-id: MRP-3311 Signed-off-by:

vc04_services contains a debug logging mechanism. The log is maintained in a shared memory area between the kernel and the firmware. Changing the sizes of the data in this area would require a firmware change which is distributed independently from the kernel binary. One of the items logged is the address of received messages. This address is a pointer, but the debugging slot used to store the information is a 32 bit integer. Luckily, this value is never interpreted by anything other then debug tools and it is expected that a human debugging the kernel interpret it. This change adds a cast to long before the original cast to int to silence the warning. Signed-off-by:

The vchiq_copy_from_user function is not portable and is consider "bad practice." Replace this function with a callback based mechanism that is passed downward on the stack. When it is actually time to copy the data, the callback is called to copy the data into the message. This callback is provided internally for userland calls through ioctls on the device. NOTE: Internal clients will need to be modified to work with the new internal API. Test Run: vchiq_test -p 1 vchiq_test -f 10 Both tests pass. Internal API Changes: Change vchi_msg_queue to: int32_t vchi_msg_queue(VCHI_SERVICE_HANDLE_T handle, ssize_t (*copy_callback)(void *context, void *dest, size_t offset, size_t maxsize), void *context, uint32_t data_size ); Remove: vchi_msg_queuev_ex vchi_msg_queuev These functions were not implemented anyway so no need to fix them. It's easier to just remove them. Signed-off-by:
