Merge branch 'for-4.15/block' of git://git.kernel.dk/linux-block

2017-11-14T23:32:19+00:00

Pull core block layer updates from Jens Axboe: "This is the main pull request for block storage for 4.15-rc1. Nothing out of the ordinary in here, and no API changes or anything like that. Just various new features for drivers, core changes, etc. In particular, this pull request contains: - A patch series from Bart, closing the whole on blk/scsi-mq queue quescing. - A series from Christoph, building towards hidden gendisks (for multipath) and ability to move bio chains around. - NVMe - Support for native multipath for NVMe (Christoph). - Userspace notifications for AENs (Keith). - Command side-effects support (Keith). - SGL support (Chaitanya Kulkarni) - FC fixes and improvements (James Smart) - Lots of fixes and tweaks (Various) - bcache - New maintainer (Michael Lyle) - Writeback control improvements (Michael) - Various fixes (Coly, Elena, Eric, Liang, et al) - lightnvm updates, mostly centered around the pblk interface (Javier, Hans, and Rakesh). - Removal of unused bio/bvec kmap atomic interfaces (me, Christoph) - Writeback series that fix the much discussed hundreds of millions of sync-all units. This goes all the way, as discussed previously (me). - Fix for missing wakeup on writeback timer adjustments (Yafang Shao). - Fix laptop mode on blk-mq (me). - {mq,name} tupple lookup for IO schedulers, allowing us to have alias names. This means you can use 'deadline' on both !mq and on mq (where it's called mq-deadline). (me). - blktrace race fix, oopsing on sg load (me). - blk-mq optimizations (me). - Obscure waitqueue race fix for kyber (Omar). - NBD fixes (Josef). - Disable writeback throttling by default on bfq, like we do on cfq (Luca Miccio). - Series from Ming that enable us to treat flush requests on blk-mq like any other request. This is a really nice cleanup. - Series from Ming that improves merging on blk-mq with schedulers, getting us closer to flipping the switch on scsi-mq again. - BFQ updates (Paolo). - blk-mq atomic flags memory ordering fixes (Peter Z). - Loop cgroup support (Shaohua). - Lots of minor fixes from lots of different folks, both for core and driver code" * 'for-4.15/block' of git://git.kernel.dk/linux-block: (294 commits) nvme: fix visibility of "uuid" ns attribute blk-mq: fixup some comment typos and lengths ide: ide-atapi: fix compile error with defining macro DEBUG blk-mq: improve tag waiting setup for non-shared tags brd: remove unused brd_mutex blk-mq: only run the hardware queue if IO is pending block: avoid null pointer dereference on null disk fs: guard_bio_eod() needs to consider partitions xtensa/simdisk: fix compile error nvme: expose subsys attribute to sysfs nvme: create 'slaves' and 'holders' entries for hidden controllers block: create 'slaves' and 'holders' entries for hidden gendisks nvme: also expose the namespace identification sysfs files for mpath nodes nvme: implement multipath access to nvme subsystems nvme: track shared namespaces nvme: introduce a nvme_ns_ids structure nvme: track subsystems block, nvme: Introduce blk_mq_req_flags_t block, scsi: Make SCSI quiesce and resume work reliably block: Add the QUEUE_FLAG_PREEMPT_ONLY request queue flag ...

xtensa/simdisk: fix compile error

block: remove __bio_kmap_atomic

2017-11-11T02:53:25+00:00

This helper doesn't buy us much over calling kmap_atomic directly. In fact in the only caller it does a bit of useless work as the caller already has the bvec at hand, and said caller would even buggy for a multi-segment bio due to the use of this helper. So just remove it. Signed-off-by: Christoph Hellwig Signed-off-by: Jens Axboe

xtensa: Convert timers to use timer_setup()

2017-11-02T22:50:33+00:00

In preparation for unconditionally passing the struct timer_list pointer to all timer callbacks, switch to using the new timer_setup() and from_timer() to pass the timer pointer explicitly. Cc: Chris Zankel Cc: Max Filippov Cc: linux-xtensa@linux-xtensa.org Signed-off-by: Kees Cook

Pull Xtensa fixes from Max Filippov: - don't use linux IRQ #0 in legacy irq domains: fixes timer interrupt assignment when it's hardware IRQ # is 0 and the kernel is built w/o device tree support - reduce reservation size for double exception vector literals from 48 to 20 bytes: fixes build on cores with small user exception vector - cleanups: use kmalloc_array instead of kmalloc in simdisk_init and seq_puts instead of seq_printf in c_show. * tag 'xtensa-20170612' of git://github.com/jcmvbkbc/linux-xtensa: xtensa: don't use linux IRQ #0 xtensa: reduce double exception literal reservation xtensa: ISS: Use kmalloc_array() in simdisk_init() xtensa: Use seq_puts() in c_show()

xtensa: ISS: Use kmalloc_array() in simdisk_init()

2017-05-08T21:53:29+00:00

* A multiplication for the size determination of a memory allocation indicated that an array data structure should be processed. Thus use the corresponding function "kmalloc_array". This issue was detected by using the Coccinelle software. * Replace the specification of a data type by a pointer dereference to make the corresponding size determination a bit safer according to the Linux coding style convention.

xtensa: ISS: update kernel command line in platform_setup

2017-03-13T20:47:20+00:00

Move platform_setup call higher in initialization sequence so that it could change kernel command line. Check command line passed to simulator in ISS platform_stup and update kernel command line if there's anything. Signed-off-by: Max Filippov

xtensa: ISS: add argc/argv simcall definitions

2017-03-13T20:47:12+00:00

There are three simcalls implemented by ISS and QEMU related to argc/argv processing: SYS_iss_argc (get number of command line arguments), SYS_iss_argv_size (get size of command line argument block) and SYS_iss_set_argv (copy command line arguments to virtual guest address). Add definitions for these calls to iss/include/platform/simcall.h Signed-off-by: Max Filippov
