Enabling the ENET PLL can cause clk_pllv3_wait_lock to sleep. See also: commit fc8726a2 ("clk: core: support clocks which requires parents enable (part 2)")." imx7s-warp does not even use the FEC interface, so we should not really configure the parent of IMX7D_ENET_AXI_ROOT_SRC in the common MX7 clock driver code. The dts file should use the assigned-clocks/assigned-clock-parents method, so simply remove the configuration of IMX7D_ENET_AXI_ROOT_SRC parent. Signed-off-by:

Michael Turquette authored
It's always nice to see families reunited, and this is equally true when talking about parent clocks and their children. However, if the orphan clk had a positive prepare_count or enable_count, then we would not migrate those counts up the parent chain correctly. This has manifested with the recent critical clocks feature, which often enables clocks very early, before their parents have been registered. Fixed by replacing the call to clk_core_reparent with calls to __clk_set_parent_{before,after}. Cc: James Liao <jamesjj.liao@mediatek.com> Cc: Erin Lo <erin.lo@mediatek.com> Signed-off-by:

According to the datasheet, SDn clocks are from the SDSRC clock. And the SDSRC has a 1/2 divider. So, we should have ".sdsrc" as an internal core clock. Otherwise, since the sdhi driver will calculate clock for a sd card using the wrong parent clock rate, and then performance will be not good.

The condition passed to read*_poll_timeout() is the break condition, i.e. wait for this condition to happen and return success. The original code assumed the opposite, resulting in a warning when the PLL clock rate was changed but never lost it's lock as far as the readout indicated. This was verified by checking the read out register value. Fixes: 1d80c142 ("clk: sunxi-ng: Add common infrastructure") Signed-off-by:

Since commit 63a4cc24, bio->bi_rw contains flags in the lower portion and the op code in the higher portions. This means that old code that relies on manually setting bi_rw is most likely going to be broken. Instead of letting that brokeness linger, rename the member, to force old and out-of-tree code to break at compile time instead of at runtime. No intended functional changes in this commit.

Jens Axboe authored
Commit abf54548 changed it from an 'rw' flags type to the newer ops based interface, but now we're effectively leaking some bdev internals to the rest of the kernel. Since we only care about whether it's a read or a write at that level, just pass in a bool 'is_write' parameter instead. Then we can also move op_is_write() and friends back under CONFIG_BLOCK protection. Reviewed-by:

Pull binfmt_misc update from James Bottomley: "This update is to allow architecture emulation containers to function such that the emulation binary can be housed outside the container itself. The container and fs parts both have acks from relevant experts. To use the new feature you have to add an F option to your binfmt_misc configuration" From the docs: "The usual behaviour of binfmt_misc is to spawn the binary lazily when the misc format file is invoked. However, this doesn't work very well in the face of mount namespaces and changeroots, so the F mode opens the binary as soon as the emulation is installed and uses the opened image to spawn the emulator, meaning it is always available once installed, regardless of how the environment changes" * tag 'binfmt-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/binfmt_misc: binfmt_misc: add F option description to documentation binfmt_misc: add persistent opened binary handler for containers fs: add filp_clone_open API

Merge tag 'xfs-rmap-for-linus-4.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/dgc/linux-xfs Pull more xfs updates from Dave Chinner: "This is the second part of the XFS updates for this merge cycle, and contains the new reverse block mapping feature for XFS. Reverse mapping allows us to track the owner of a specific block on disk precisely. It is implemented as a set of btrees (one per allocation group) that track the owners of allocated extents. Effectively it is a "used space tree" that is updated when we allocate or free extents. i.e. it is coherent with the free space btrees we already maintain and never overlaps with them. This reverse mapping infrastructure is the building block of several upcoming features - reflink, copy-on-write data, dedupe, online metadata and data scrubbing, highly accurate bad sector/data loss reporting to users, and significantly improved reconstruction of damaged and corrupted filesystems. There's a lot of new stuff coming along in the next couple of cycles,a nd it all builds in the rmap infrastructure. As such, it's a huge chunk of new code with new on-disk format features and internal infrastructure. It warns at mount time as an experimental feature and that it may eat data (as we do with all new on-disk features until they stabilise). We have not released userspace suport for it yet - userspace support currently requires download from Darrick's xfsprogs repo and build from source, so the access to this feature is really developer/tester only at this point. Initial userspace support will be released at the same time kernel with this code in it is released. The new rmap enabled code regresses 3 xfstests - all are ENOSPC related corner cases, one of which Darrick posted a fix for a few hours ago. The other two are fixed by infrastructure that is part of the upcoming reflink patchset. This new ENOSPC infrastructure requires a on-disk format tweak required to keep mount times in check - we need to keep an on-disk count of allocated rmapbt blocks so we don't have to scan the entire btrees at mount time to count them. This is currently being tested and will be part of the fixes sent in the next week or two so users will not be exposed to this change" * tag 'xfs-rmap-for-linus-4.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/dgc/linux-xfs: (52 commits) xfs: move (and rename) the deferred bmap-free tracepoints xfs: collapse single use static functions xfs: remove unnecessary parentheses from log redo item recovery functions xfs: remove the extents array from the rmap update done log item xfs: in btree_lshift, only allocate temporary cursor when needed xfs: remove unnecesary lshift/rshift key initialization xfs: remove the get*keys and update_keys btree ops pointers xfs: enable the rmap btree functionality xfs: don't update rmapbt when fixing agfl xfs: disable XFS_IOC_SWAPEXT when rmap btree is enabled xfs: add rmap btree block detection to log recovery xfs: add rmap btree geometry feature flag xfs: propagate bmap updates to rmapbt xfs: enable the xfs_defer mechanism to process rmaps to update xfs: log rmap intent items xfs: create rmap update intent log items xfs: add rmap btree insert and delete helpers xfs: convert unwritten status of reverse mappings xfs: remove an extent from the rmap btree xfs: add an extent to the rmap btree ...

Pull block fixes from Jens Axboe: "Here's the second round of block updates for this merge window. It's a mix of fixes for changes that went in previously in this round, and fixes in general. This pull request contains: - Fixes for loop from Christoph - A bdi vs gendisk lifetime fix from Dan, worth two cookies. - A blk-mq timeout fix, when on frozen queues. From Gabriel. - Writeback fix from Jan, ensuring that __writeback_single_inode() does the right thing. - Fix for bio->bi_rw usage in f2fs from me. - Error path deadlock fix in blk-mq sysfs registration from me. - Floppy O_ACCMODE fix from Jiri. - Fix to the new bio op methods from Mike. One more followup will be coming here, ensuring that we don't propagate the block types outside of block. That, and a rename of bio->bi_rw is coming right after -rc1 is cut. - Various little fixes" * 'for-linus' of git://git.kernel.dk/linux-block: mm/block: convert rw_page users to bio op use loop: make do_req_filebacked more robust loop: don't try to use AIO for discards blk-mq: fix deadlock in blk_mq_register_disk() error path Include: blkdev: Removed duplicate 'struct request;' declaration.
