The workqueues "ioc->reset_work_q" and "ioc->fw_event_q" queue a single work item &ioc->fault_reset_work and &fw_event->work, respectively and hence don't require ordering. Hence, they have been converted to use alloc_workqueue(). The WQ_MEM_RECLAIM flag has been set to ensure forward progress under memory pressure since the workqueue belongs to a storage driver which is being used on a memory reclaim path. Since there are fixed number of work items, explicit concurrency limit is unnecessary here. Signed-off-by:

The workqueue "fc_rescan_work_q" queues multiple work items viz &ioc->fc_rescan_work, &ioc->fc_lsc_work, &ioc->fc_setup_reset_work, which require strict execution ordering. Hence, an ordered dedicated workqueue has been used. WQ_MEM_RECLAIM has been set since the workqueue is belongs to a storage driver which is being used on a memory reclaim path and hence, requires forward progress under memory pressure. Signed-off-by:

The 2nd parameter of 'find_first_bit' is the number of bits to search. In this case, we are passing 'sizeof(unsigned long)' which is likely to be 4. It is likely that the number of bits in a long was expected here, so use BITS_PER_LONG instead. Signed-off-by:

Calculating the maximum timeout that a user can set via the SG_SET_TIMEOUT ioctl involves multiplying INT_MAX by USER_HZ/HZ. If USER_HZ is larger than HZ then this results in an overflow when performed as a 32 bit integer calculation, resulting in compiler warnings such as the following: drivers/scsi/sg.c: In function 'sg_ioctl': drivers/scsi/sg.c:91:67: warning: integer overflow in expression [-Woverflow] #define MULDIV(X,MUL,DIV) ((((X % DIV) * MUL) / DIV) + ((X / DIV) * MUL)) ^ drivers/scsi/sg.c:887:14: note: in expansion of macro 'MULDIV' if (val >= MULDIV (INT_MAX, USER_HZ, HZ)) ^ drivers/scsi/sg.c:91:67: warning: integer overflow in expression [-Woverflow] #define MULDIV(X,MUL,DIV) ((((X % DIV) * MUL) / DIV) + ((X / DIV) * MUL)) ^ drivers/scsi/sg.c:888:13: note: in expansion of macro 'MULDIV' val = MULDIV (INT_MAX, USER_HZ, HZ); ^ Avoid this overflow by performing the (constant) arithmetic on 64 bit integers, which ensures that overflow from multiplying the 32 bit values cannot occur. When converting the result back to a 32 bit integer use min_t to ensure that we don't simply truncate a value beyond INT_MAX to a 32 bit integer, but instead use INT_MAX where the result was larger than it. As the values are all compile time constant the 64 bit arithmetic should have no runtime cost. Signed-off-by:

The ibmvfc driver currently doesn't support FC Class 3 Error Recovery. However, it is simply a matter of informing the VIOS that the payload expects to use sequence level error recovery via a bit flag in the ibmvfc_cmd structure. This patch adds a module parameter to enable error recovery support at boot time. When enabled the RETRY service parameter bit is set during PRLI, and ibmvfc_cmd->flags includes the IBMVFC_CLASS_3_ERR bit. Signed-off-by:

Runtime PM should be configured already once we call device_add. See also the description in this mail thread https://lists.linuxfoundation.org/pipermail/linux-pm/2009-November/023198.html or the order of calls e.g. in usb_new_device. The changed order also helps to avoid scenarios where runtime pm for &shost->shost_gendev is activated whilst the parent is suspended, resulting in error message "runtime PM trying to activate child device hostx but parent yyy is not active". In addition properly reverse the runtime pm calls in the error path. Signed-off-by:

This patch implements functions for pushing HCAM (host controlled asynchronous messages) error buffers to userspace through sysfs attributes. Reads to the "async_err_log" attribute will result in a single HCAM buffer being copied to userspace; one can process the next HCAM buffer by writing any string to the same attribute. A new list was added to the ioa_cfg structure to store the HCAM buffers for later reporting. We also send a KOBJ_CHANGE event whenever a new HCAM buffer is made available to userspace. Signed-off-by:
