| * [SCSI] qla4xxx: Use polling mode for disable interrupt mailbox completionSarang Radke2011-03-23
| | | | | | | | | | | | | | | | | | | | | | | | Disable Interrupt MBX completion will disable the interrupt on successful completion. Fixed the bug where driver was waiting for Interrupt to come in for its completion. Now driver will poll for disable interrupt MBX completion.

| * [SCSI] bnx2fc: IO completion not processed due to missed wakeupBhanu Gollapudi2011-03-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Driver does not detect a new CQE (completion queue entry) if a thread receives the wakup when it is in TASK_RUNNING state. Fix is to set the state to TASK_INTERRUPTIBLE while holding the fp_work_lock. Also, Use __set_current_task() since it is now set inside a spinlock with synchronization. Two other related optimizations: 1. After we exit the while (!kthread_should_stop()) loop, use __set_current_state() since synchronization is no longer needed. 2. Remove set_current_state(TASK_RUNNING) after schedule() since it should always be TASK_RUNNING after schedule().

| * [SCSI] ses: add subenclosure supportJames Bottomley2011-03-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There have been many complaints that an enclosure with subenclosures isn't attached to by the ses driver. Until now, though, no-one had been willing to provide access to one. Subenclosures are added simply by flattening the tree (i.e. all subenclosure devices show up under the one main device). This may have consequences if the naming is only unique per subenclosure, but that's a bug for another day. The tested array had no page 7, so no device naming at all. It also only had the disk devices on one of its subenclosures (all the others had power, fans, temperature and various sensors), so testing of this is fairly rudimentary.

| * [SCSI] bnx2fc: common free list for cleanup commandsBhanu Gollapudi2011-03-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Cleanup commands are issued to the firmware to cleanup any stuck ios that are supposed to be implicitly aborted. In the worst case we can have all scsi ios filling up the free_list and we may not be able to allocate cleanup tasks. So the driver has to reserve free_list entries to be able to allocate the cleanup tasks. This reserve free_list common to all cpus is allocated as one additional entry in the per cpu free_lists. In bnx2fc_cmd_alloc(), there is a related fix to use get_cpu() for the free_list_index. This will prevent using the wrong index if the CPU is preempted.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With kernel debugging enabled, holding cq_lock when calling bnx2fc_free_session_resc() which calls iounmap() leads to a warning stack trace [INFO: HARDIRQ-safe -> HARDIRQ-unsafe lock order detected]. iounmap() grabs a HARDIRQ-unsafe vmlist lock, so holding spin_lock_bh(cq_lock) when calling iounmap() will trigger the LOCKDEP warning.

I believe this version adresses all comments it has gathered over time. Please apply or reject with a reason. The benefits are: - makes the code easier to read. Lots of sequential derefs of the same pointers is not easy on the eye. - theoretically at least, just dereferencing the pointers once can allow the compiler to generally slightly faster code, so in theory this could also be a micro speed optimization. - reduces size of object file (tiny effect: on x86-64, in at least one configuration, the text size decreased from 9439 bytes to 9400) - removes some pointless (mostly trailing) whitespace.
