When a process is doing Random Write with O_DSYNC flag the I/O wait are not accounted in the kernel (get_cpu_iowait_time_us). This is preventing the governor or the cpufreq driver to account for I/O wait and thus use the right pstate Signed-off-by: NStephane Gasparini <stephane.gasparini@linux.intel.com> Signed-off-by: NPhilippe Longepe <philippe.longepe@linux.intel.com> Signed-off-by: NJens Axboe <axboe@fb.com>

In case /dev/fdX is open with O_NDELAY / O_NONBLOCK, floppy_open() immediately succeeds, without performing any further media / controller preparations. That's "correct" wrt. the NODELAY flag, but is hardly correct wrt. the rest of the floppy driver, that is not really O_NONBLOCK ready, at all. Therefore it's not too surprising, that subsequent attempts to work with the filedescriptor produce bad results. Namely, syzkaller tool has been able to livelock mmap() on the returned fd to keep waiting on the page unlock bit forever. Quite frankly, I have trouble defining what non-blocking behavior would be for floppies. Is waiting ages for the driver to actually succeed reading a sector blocking operation? Is waiting for drive motor to start blocking operation? How about in case of virtualized floppies? One option would be returning EWOULDBLOCK in case O_NDLEAY / O_NONBLOCK is being passed to open(). That has a theoretical potential of breaking some arcane and archaic userspace though. Let's take a more conservative aproach, and accept the O_NDLEAY flag, and let the driver behave as usual. While at it, clean up a bit handling of !(mode & (FMODE_READ|FMODE_WRITE)) case and return EINVAL instead of succeeding as well. Spotted by syzkaller tool.

System block allows the device to initialize with its configured media manager. The system blocks is written to disk, and read again when media manager is determined. For this to work, the backend must store the data. Device drivers, such as null_blk, does not have any backend storage. This patch allows the media manager to be initialized without a storage backend. It also fix incorrect configuration of capabilities in null_blk, as it does not support get/set bad block interface.

This patch fixes an error on the calculation of intersecting logical addresses; it contemplates the case where a new request including several addresses intersects with a single locked address. This case is typical when multiple pages are sent in a new request, while GC - which at the moment sends one address at the time - is running.

由 Jiri Kosina 提交于
floppy_revalidate() doesn't perform any error handling on lock_fdc() result. lock_fdc() might actually be interrupted by a signal (it waits for fdc becoming non-busy interruptibly). In such case, floppy_revalidate() proceeds as if it had claimed the lock, but it fact it doesn't. In case of multiple threads trying to open("/dev/fdX"), this leads to serious corruptions all over the place, because all of a sudden there is no critical section protection (that'd otherwise be guaranteed by locked fd) whatsoever. While at this, fix the fact that the 'interruptible' parameter to lock_fdc() doesn't make any sense whatsoever, because we always wait interruptibly anyway. Most of the lock_fdc() callsites do properly handle error (and propagate EINTR), but floppy_revalidate() and floppy_check_events() don't. Fix this. Spotted by 'syzkaller' tool.

This reverts commit 14e46e04. This ends up doing sysfs operations from deep in balance (where we should be GFP_NOFS) and under heavy balance load, we're making races against sysfs internals. Revert it for now while we figure things out. Signed-off-by: NChris Mason <clm@fb.com>

On Broxton, to make sure the reset controller works properly, MISCBDCGE bit (bit 6) in CGCTL (0x48) of PCI configuration space need be cleared before reset and set back to 1 after reset. Otherwise, it may prevent the CORB/RIRB logic from being reset.

Trying to build a kernel for ARC with both options CONFIG_COMPILE_TEST and CONFIG_IOMMU_IO_PGTABLE_LPAE enabled (e.g. as a result of "make allyesconfig") results in the following build failure: | CC drivers/iommu/io-pgtable-arm.o | linux/drivers/iommu/io-pgtable-arm.c: In | function ‘__arm_lpae_alloc_pages’: | linux/drivers/iommu/io-pgtable-arm.c:221:3: | error: implicit declaration of function ‘dma_map_single’ | [-Werror=implicit-function-declaration] | dma = dma_map_single(dev, pages, size, DMA_TO_DEVICE); | ^ | linux/drivers/iommu/io-pgtable-arm.c:221:42: | error: ‘DMA_TO_DEVICE’ undeclared (first use in this function) | dma = dma_map_single(dev, pages, size, DMA_TO_DEVICE); | ^ Since IOMMU_IO_PGTABLE_LPAE depends on DMA API, io-pgtable-arm.c should include linux/dma-mapping.h.

Pull minor tracing fixes from Steven Rostedt: "This includes three minor fixes, mostly due to cut-and-paste issues. The first is a cut and paste issue that changed the amount of stack to skip when tracing a stack dump from 0 to 6, which basically made the stack disappear for small stack traces. The second fix is just removing an unused field in a struct that is no longer used, and currently just wastes space. The third is another cut-and-paste fix that had a tracepoint recording the wrong field (it was recording the previous field a second time)" * tag 'trace-v4.5-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: tracing/dma-buf/fence: Fix timeline str value on fence_annotate_wait_on ftrace: Remove unused nr_trampolines var tracing: Fix stacktrace skip depth in trace_buffer_unlock_commit_regs()

Merge branch 'drm-rockchip-next-fixes-2016-01-22' of https://github.com/markyzq/kernel-drm-rockchip into drm-fixes Here are some fixes for drm/rockchip, these fixes base on drm-next. These fixes works on my popmetal(rk3288) board. About patch: drm/atomic-helper: Export framebuffer_changed() Daniel Vetter ack for merging it through rockchip git trees, so framebuffer_changed() can be reused by drm/rockchip. All others looks good, so I'd like you can land them. * 'drm-rockchip-next-fixes-2016-01-22' of https://github.com/markyzq/kernel-drm-rockchip: drm/rockchip: respect CONFIG_DRM_FBDEV_EMULATION drm/rockchip: fix wrong pitch/size using on gem drm/rockchip: explain why we can't wait_for_vblanks drm/rockchip: don't wait for vblank if fb hasn't changed drm/atomic-helper: Export framebuffer_changed() drm/rockchip/dsi: fix handling mipi_dsi_pixel_format_to_bpp result drm/rockchip: vop: fix mask when updating interrupts drm/rockchip: cleanup unnecessary export symbol drm/rockchip: Don't build rockchip_drm_vop as modules
