There's already a fc_vport_termintate() call exported by the transport. This patch adds a symmetric call to the API to allow an NPIV-capable LLD to instantiate vports sans user intervention. Additional comments/updates: Re: scsi_fc_transport.txt Add a function prototype for fc_vport_terminate similar to what's done for fc_vport_create Re: fc_vport_create I recommend we pass the channel number in fc_vport_create rather than fixing it at zero. Also, ids->vport_type should be set to FC_PORTTYPE_NPIV prior to calling fc_vport_create. The comment is also meaningless.

This patch adds the ability to print sizes in either units of 10^3 (SI) or 2^10 (Binary) units. It rounds up to three significant figures and can be used for either memory or storage capacities. Oh, and I'm fully aware that 64 bits is only 16EiB ... the Zetta and Yotta units are added for future proofing against the day we have 128 bit computers ...

Brian King <brking@linux.vnet.ibm.com> reported that fibre channel devices can oops during scanning if their ports block (because the device goes from CREATED -> BLOCK -> RUNNING rather than CREATED -> BLOCK -> CREATED). Fix this by adding a new state: CREATED_BLOCK which can only transition back to CREATED and disallow the CREATED -> BLOCK transition.

This patch adds scsi netlink recieve and event support for transport and scsi LLDD's. It is a reimplementation of the patch posted last week by David Somayajulu. http://marc.info/?l=linux-scsi&m=121745486221819&w=2 There are a few things done differently: - Transport support is included - Event delivery is included - The vendor message is now its own unique message type, considered part of the generic "SCSI Transport". - LLDD entry points are now registered rather than included in the scsi_host_template. Background: When I started to implement the event handler via template, I had to either: muck up scsi_add_host and scsi_remove_host; or have the event handler search all possible shosts. Neither was acceptable. Moving to a registration solves this, and also limits the scope of the changes to something that could be backported to a distro without breaking an already-released-distro kabi. However, I admit it isn't as elegant, as the passing of the LLDD host template in the registration and the complexity around dynamic add/remove shows. - The receive path was augmented to require a unique identifier for the LLDD before the message was allowed to be handed off to the driver. Given how quickly very fatal errors occur if there's msg mismatches (which I saw in testing my own tools :), I believe this to be a very good thing. The id plays off the vendor id scheme already introduced for the vendor unique event messages used by FC. Additionally, the id use as the basis of the registration/deregistration. - Send assist functions, for both the transport and LLDDs are included.

This patch cleans up the behavior of scsi_host_lookup(). The original implementation attempted to use the dual role of either returning a pointer value, or a negative error code. User's needed to use IS_ERR() to check the result. Additionally, the IS_ERR() macro never checks for when a NULL pointer was returned, so a NULL pointer actually passes with a success case. Note: scsi_host_get(), used by scsi_host_lookup(), can return a NULL pointer. Talk about a mudhole for the unitiated to step into.... This patch converts scsi_host_lookup() to return either NULL or a valid pointer. The consumers were updated for the change.

When we initialise a compound page we initialise the page flags and head page pointer for all base pages spanned by that page. When we initialise a gigantic page (a page of order greater than or equal to MAX_ORDER) we have to initialise more than MAX_ORDER_NR_PAGES pages. Currently we assume that all elements of the mem_map in this page are contigious in memory. However this is only guarenteed out to MAX_ORDER_NR_PAGES pages, and with SPARSEMEM enabled they will not be contigious. This leads us to walk off the end of the first section and scribble on everything which follows, BAD. When we reach a MAX_ORDER_NR_PAGES boundary we much locate the next section of the mem_map. As gigantic pages can only be maximally aligned we know this will occur at exact multiple of MAX_ORDER_NR_PAGES pages from the start of the page. This is a bug fix for the gigantic page support in hugetlbfs. Credit to Mel Gorman for spotting the issue.

The previous patch db203d53 ("mm: tiny-shmem fix lock ordering: mmap_sem vs i_mutex") to fix the lock ordering in tiny-shmem breaks shared anonymous and IPC memory on NOMMU architectures because it was using the expanding truncate to signal ramfs to allocate a physically contiguous RAM backing the inode (otherwise it is unusable for "memory mapping" it to userspace). However do_truncate is what caused the lock ordering error, due to it taking i_mutex. In this case, we can actually just call ramfs directly to allocate memory for the mapping, rather than go via truncate.

__test_page_isolated_in_pageblock() in mm/page_isolation.c has a comment saying that the caller must hold zone->lock. But the only caller of that function, test_pages_isolated(), does not hold zone->lock and the lock is also not acquired anywhere before. This patch adds the missing zone->lock to test_pages_isolated(). We reproducibly run into BUG_ON(!PageBuddy(page)) in __offline_isolated_pages() during memory hotplug stress test, see trace below.

Fix the IRQ handling on the MN10300 arch. This patch makes a number of significant changes: (1) It separates the irq_chip definition for edge-triggered interrupts from the one for level-triggered interrupts. This is necessary because the MN10300 PIC latches the IRQ channel's interrupt request bit (GxICR_REQUEST), even after the device has ceased to assert its interrupt line and the interrupt channel has been disabled in the PIC. So for level-triggered interrupts we need to clear this bit when we re-enable - which is achieved by setting GxICR_DETECT but not GxICR_REQUEST when writing to the register. Not doing this results in spurious interrupts occurring because calling mask_ack() at the start of handle_level_irq() is insufficient - it fails to clear the REQUEST latch because the device that caused the interrupt is still asserting its interrupt line at this point. (2) IRQ disablement [irq_chip::disable_irq()] shouldn't clear the interrupt request flag for edge-triggered interrupts lest it lose an interrupt. (3) IRQ unmasking [irq_chip::unmask_irq()] also shouldn't clear the interrupt request flag for edge-triggered interrupts lest it lose an interrupt. (4) The end() operation is now left to the default (no-operation) as __do_IRQ() is compiled out. This may affect misrouted_irq(), but according to Thomas Gleixner it's the correct thing to do. (5) handle_level_irq() is used for edge-triggered interrupts rather than handle_edge_irq() as the MN10300 PIC latches interrupt events even on masked IRQ channels, thus rendering IRQ_PENDING unnecessary. It is sufficient to call mask_ack() at the start and unmask() at the end. (6) For level-triggered interrupts, ack() is now NULL as it's not used, and there is no effective ACK function on the PIC. mask_ack() is now the same as mask() as the latch continues to latch, even when the channel is masked. Further, the patch discards the disable() op implementation as its now the same as the mask() op implementation, which is used instead. It also discards the enable() op implementations as they're now the same as the unmask() op implementations, which are used instead.
