2016-05-09staging: unisys: visorinput: handle_locking_key() simplificationsTim Sell1-11/+7
By directly returning for the error-case, a test was eliminated. Also, the old_state variable was removed as it was not necessary, and some redundant parens were removed.

2016-05-09staging: unisys: visorhba: fail gracefully for thread creation failuresTim Sell1-26/+28
Previously, if visorhba ever failed to create its thread, it would have subsequently attempted to do a kthread_stop() on an invalid task_struct pointer. This was fixed via the new visor_thread_stop() function, which validates the task_struct pointer before doing the kthread_stop(). Also, the other thread-related fields in visor_thread_info (has_stopped and id) were not being used, so visor_thead_info was just removed. We also now spit out an error message if thread creation fails.

Enables support of different map-on-demand values per NI. This is required to support OPA coexistence with MLX5 cards. MLX5 does not support FMR, which is enabled via map-on-demand. However OPA's performance is greatly enahanced when FMR is enabled. In order to enable coexistence of both of these two types of cards we need to be able to set different map-on-demand values for both NIs.

2016-05-09staging: lustre: fid: packing ost_idx in IDIFFan Yong2-41/+57
For a normal FID, we can know on which target the related object is allocated via querying FLDB; but it is not true for an IDIF. To locate the OST via the given IDIF, when the IDIF is generated, we pack the OST index in it. Then for any given FID, in spite of t is a normal FID or not, we has the method to know which target it belongs to. That is useful for LFSCK. For old IDIF, the OST index is not part of the IDIF, means that ifferent OSTs may have the same IDIFs, that may cause the IFID in LMA does not match the read FID. Under such case, we need to make some compatible check to avoid to trigger unexpected. tgt_validate_obdo() converts the ostid contained in the RPC body to fid and changes the "struct ost_id" union, then the users can access ost_id::oi_fid directly without call ostid_to_fid() again.

2016-05-09staging: lustre: osc: Allow lock to be canceled at ENQ timeAlexander Boyko2-0/+4
A cl_lock can be canceled when it's in CLS_ENQUEUED state. We can't unuse this kind of lock in lov_lock_unuse() because it will bring this lock into CLS_NEW state and then confuse osc_lock_upcall().

2016-05-04drivers: replace dev->trans_start accesses with dev_trans_startFlorian Westphal2-2/+2
a trans_start struct member exists twice: - in struct net_device (legacy) - in struct netdev_queue Instead of open-coding dev->trans_start usage to obtain the current trans_start value, use dev_trans_start() instead. This is not exactly the same, as dev_trans_start also considers the trans_start values of the netdev queues owned by the device and provides the most recent one. For legacy devices this doesn't matter as dev_trans_start can cope with netdev trans_start values of 0 (they are ignored). This is a prerequisite to eventual removal of dev->trans_start.

2016-05-03staging: wilc1000: fix infoleak in wilc_wfi_cfgoperationsKangjie Lu1-0/+1
"mac" is an array allocated in stack without being initialized, and will be sent out via "nla_put". The dump_station() is supposed to initialize the mac address; otherwise, sensitive data in kernel stack will be leaked. To fix this, copy the mac address to it.
