Turns out the USB support for a Renesas board was developed on a pre-release board that ended up being changed before shipping. To avoid breakage on those boards, and avoid confusion, it's a reasonable idea to patch now instead of later. There are no known users of the pre-release variant any more" * tag 'armsoc-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: ARM: dts: porter: remove enable prop from HS-USB device node 06 March 2016, 22:14:54 UTC

The KVM/QEMU enabling for NVDIMMs has recently reached the point where it is able to accept some ACPI _DSM requests from a guest VM. However they immediately found that the 4.5-rc kernel is unusable because the kernel's 'nfit' driver fails to load upon seeing a valid "not supported" response from the virtual BIOS for an address range scrub command. It is not mandatory that a platform implement address range scrubbing, so this fix from Vishal properly treats the 'not supported' response as 'skip scrubbing and continue loading the driver'" * 'libnvdimm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm: nfit: Continue init even if ARS commands are unimplemented 05 March 2016, 02:47:18 UTC

I cut back to the bare necessities, the patch is still larger than it usually would be at this time, due to the number of NVMe fixes in there. This pull request contains: - The 4 core fixes from Ming, that fix both problems with exceeding the virtual boundary limit in case of merging, and the gap checking for cloned bio's. - NVMe fixes from Keith and Christoph: - Regression on larger user commands, causing problems with reading log pages (for instance). This touches both NVMe, and the block core since that is now generally utilized also for these types of commands. - Hot removal fixes. - User exploitable issue with passthrough IO commands, if !length is given, causing us to fault on writing to the zero page. - Fix for a hang under error conditions - And finally, the current series regression for umount with cgroup writeback, where the final flush would happen async and hence open up window after umount where the device wasn't consistent. fsck right after umount would show this.

But this prevented filtering on a comm field that is within a trace event (like sched_migrate_task). When trying to filter on when a program migrated, this change prevented the filtering of the sched_migrate_task. To fix this, the event fields are examined first, and then the extra fields like "comm" and "cpu" are examined. Also, instead of testing to assign the comm filter function based on the field's name, the generic comm field is given a new filter type (FILTER_COMM). When this field is used to filter the type is checked. The same is done for the cpu filter field. Two new special filter types are added: "COMM" and "CPU". This allows users to still filter the tasks comm for events that have "comm" as one of their fields, in cases that users would like to filter sched_migrate_task on the comm of the task that called the event, and not the comm of the task that is being migrated" * tag 'trace-fixes-v4.5-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: tracing: Do not have 'comm' filter override event 'comm' field 05 March 2016, 00:57:04 UTC

e57cbaf Steven Rostedt (Red Hat) 03 March 2016, 22:18:20 UTC tracing: Do not have 'comm' filter override event 'comm' field Commit 9f61668073a8d "tracing: Allow triggers to filter for CPU ids and process names" added a 'comm' filter that will filter events based on the current tasks struct 'comm'. But this now hides the ability to filter events that have a 'comm' field too. For example, sched_migrate_task trace event. That has a 'comm' field of the task to be migrated. echo 'comm == "bash"' > events/sched_migrate_task/filter will now filter all sched_migrate_task events for tasks named "bash" that migrates other tasks (in interrupt context), instead of seeing when "bash" itself gets migrated. This fix requires a couple of changes. 1) Change the look up order for filter predicates to look at the events fields before looking at the generic filters. 2) Instead of basing the filter function off of the "comm" name, have the generic "comm" filter have its own filter_type (FILTER_COMM). Test against the type instead of the name to assign the filter function. 3) Add a new "COMM" filter that works just like "comm" but will filter based on the current task, even if the trace event contains a "comm" field. Do the same for "cpu" field, adding a FILTER_CPU and a filter "CPU".

909c3a2 Filipe Manana 02 March 2016, 15:49:38 UTC Btrfs: fix loading of orphan roots leading to BUG_ON When looking for orphan roots during mount we can end up hitting a BUG_ON() (at root-item.c:btrfs_find_orphan_roots()) if a log tree is replayed and qgroups are enabled. This is because after a log tree is replayed, a transaction commit is made, which triggers qgroup extent accounting which in turn does backref walking which ends up reading and inserting all roots in the radix tree fs_info->fs_root_radix, including orphan roots (deleted snapshots).

a1a0e23 Tejun Heo 29 February 2016, 23:28:53 UTC writeback: flush inode cgroup wb switches instead of pinning super_block If cgroup writeback is in use, inodes can be scheduled for asynchronous wb switching. Before 5ff8eaac1636 ("writeback: keep superblock pinned during cgroup writeback association switches"), this could race with umount leading to super_block being destroyed while inodes are pinned for wb switching. 5ff8eaac1636 fixed it by bumping s_active while wb switches are in flight; however, this allowed in-flight wb switches to make umounts asynchronous when the userland expected synchronosity - e.g. fsck immediately following umount may fail because the device is still busy. This patch removes the problematic super_block pinning and instead makes generic_shutdown_super() flush in-flight wb switches. wb switches are now executed on a dedicated isw_wq so that they can be flushed and isw_nr_in_flight keeps track of the number of in-flight wb switches so that flushing can be avoided in most cases. v2: Move cgroup_writeback_umount() further below and add MS_ACTIVE check in inode_switch_wbs() as Jan an Al suggested.

It is up to the caller to ensure no active namespace scanning is occuring. To ensure no scan work occurs, the nvme pci driver adds a removing state to the controller device to avoid queueing scan work during removal. The work is flushed after setting the state, so no new scan work can be queued. The lockless removal allows the driver to cleanup a namespace request_queue if the controller fails during removal.

The arguments themselves do not need to be aligned to a power of two, but aligning them up to the largest basic type alignment (u64) on common ABIs is a good thing to do. The patch changes the size of the reserved fields to 5 or 6 u32's and aligns the size of the struct to 8 bytes so we do no longer depend on the compiler to perform the alignment.

3d943c9 Majd Dibbiny 14 February 2016, 16:35:52 UTC IB/{core, mlx5}: Fix input len in vendor part of create_qp/srq Currently, the inlen field of the vendor's part of the command doesn't match the command buffer. This happens because the inlen accommodates ib_uverbs_cmd_hdr which is deducted from the in buffer. This is problematic since the vendor function could be called either from the legacy verb (where the input length mismatches the actual length) or by the extended verb (where the length matches). The vendor has no idea which function calls it and therefore has no way to know how the length variable should be treated. Fixing this by aligning the inlen to the correct length. All vendor drivers either assumed that inlen >= sizeof(vendor_uhw_cmd) or just failed wrongly (mlx5) and fixed in this patch.

39680f5 Linus Torvalds 01 March 2016, 19:56:22 UTC userfaultfd: don't block on the last VM updates at exit time The exit path will do some final updates to the VM of an exiting process to inform others of the fact that the process is going away. That happens, for example, for robust futex state cleanup, but also if the parent has asked for a TID update when the process exits (we clear the child tid field in user space). However, at the time we do those final VM accesses, we've already stopped accepting signals, so the usual "stop waiting for userfaults on signal" code in fs/userfaultfd.c no longer works, and the process can become an unkillable zombie waiting for something that will never happen. To solve this, just make handle_userfault() abort any user fault handling if we're already in the exit path past the signal handling state being dead (marked by PF_EXITING). This VM special case is pretty ugly, and it is possible that we should look at finalizing signals later (or move the VM final accesses earlier). But in the meantime this is a fairly minimally intrusive fix.
