2019-12-03ALSA: hda: hdmi - Keep old slot assignment behavior for Intel platformsTakashi Iwai1-6/+3
The commit 609f5485344b ("ALSA: hda: hdmi - preserve non-MST PCM routing for Intel platforms") tried to restore the old behavior wrt assignment of the PCM slot for Intel platforms, but this didn't do it right. As found in the later discussion, a positive pipe id on Intel platforms can be passed for single monitor attachment case. This patch reverts the previous attempt and applies a simpler workaround instead. Actually, for Intel platforms, we can handle as if per_pin->dev_id=0, assign the primary slot at the first try. This assures the compatible behavior with the previous versions regarding the slot assignment.

2019-12-03block: set the zone size in blk_revalidate_disk_zones atomicallyChristoph Hellwig3-29/+35
The current zone revalidation code has a major problem in that it doesn't update the zone size and q->nr_zones atomically, leading to a short window where an out of bounds access to the zone arrays is possible. To fix this move the setting of the zone size into the crticial sections blk_revalidate_disk_zones so that it gets updated together with the zone bitmaps and q->nr_zones. This also slightly simplifies the caller as it deducts the zone size from the report_zones. This change also allows to check for a power of two zone size in generic code.

2019-12-03drm/i915/ehl: Make icp_digital_port_connected() use phy instead of portMatt Roper1-7/+5
When looking at SDEISR to determine the connection status of combo outputs, we should use the phy index rather than the port index. Although they're usually the same thing, EHL's DDI-D (port D) is attached to PHY-A and SDEISR doesn't even have bits for a "D" output. It's also possible that future platforms may map DDIs (the internal display engine programming units) to PHYs (the output handling on the IO side) in ways where port!=phy, so let's look at the PHY index by default. v2: Rename to intel_combo_phy_connected.

2019-12-02io_uring: ensure async punted read/write requests copy iovecJens Axboe1-62/+181
Currently we don't copy the iovecs when we punt to async context. This can be problematic for applications that store the iovec on the stack, as they often assume that it's safe to let the iovec go out of scope as soon as IO submission has been called. This isn't always safe, as we will re-copy the iovec once we're in async context. Make this 100% safe by copying the iovec just once. With this change, applications may safely store the iovec on the stack for all cases. Reported-by: 李通洲 <[email protected]> Signed-off-by: Jens Axboe <[email protected]>
2019-12-02xfs: don't check for AG deadlock for realtime files in bunmapiOmar Sandoval1-1/+1
Commit 5b094d6dac04 ("xfs: fix multi-AG deadlock in xfs_bunmapi") added a check in __xfs_bunmapi() to stop early if we would touch multiple AGs in the wrong order. However, this check isn't applicable for realtime files. In most cases, it just makes us do unnecessary commits. However, without the fix from the previous commit ("xfs: fix realtime file data space leak"), if the last and second-to-last extents also happen to have different "AG numbers", then the break actually causes __xfs_bunmapi() to return without making any progress, which sends xfs_itruncate_extents_flags() into an infinite loop.

2019-12-02xfs: fix realtime file data space leakOmar Sandoval1-11/+14
Realtime files in XFS allocate extents in rextsize units. However, the written/unwritten state of those extents is still tracked in blocksize units. Therefore, a realtime file can be split up into written and unwritten extents that are not necessarily aligned to the realtime extent size. __xfs_bunmapi() has some logic to handle these various corner cases. Consider how it handles the following case: 1. The last extent is unwritten. 2. The last extent is smaller than the realtime extent size. 3. startblock of the last extent is not aligned to the realtime extent size, but startblock + blockcount is. In this case, __xfs_bunmapi() calls xfs_bmap_add_extent_unwritten_real() to set the second-to-last extent to unwritten. This should merge the last and second-to-last extents, so __xfs_bunmapi() moves on to the second-to-last extent. However, if the size of the last and second-to-last extents combined is greater than MAXEXTLEN, xfs_bmap_add_extent_unwritten_real() does not merge the two extents. When that happens, __xfs_bunmapi() skips past the last extent without unmapping it, thus leaking the space. Fix it by only unwriting the minimum amount needed to align the last extent to the realtime extent size, which is guaranteed to merge with the last extent.

2019-12-02io_uring: add general async offload contextJens Axboe1-24/+32
Right now we just copy the sqe for async offload, but we want to store more context across an async punt. In preparation for doing so, put the sqe copy inside a structure that we can expand. With this pointer added, we can get rid of REQ_F_FREE_SQE, as that is now indicated by whether req->io is NULL or not. No functional changes in this patch.

2019-12-02block: don't send uevent for empty disk when not invalidatingEric Biggers1-1/+1
Commit 6917d0689993 ("block: merge invalidate_partitions into rescan_partitions") caused a regression where systemd-udevd spins forever using max CPU starting at boot time. It's caused by a behavior change where a KOBJ_CHANGE uevent is now sent in a case where previously it wasn't. Restore the old behavior.
