2021-04-12vfio/mdev: Correct the function signatures for the mdev_type_attributesJason Gunthorpe
The driver core standard is to pass in the properly typed object, the properly typed attribute and the buffer data. It stems from the root kobject method: ssize_t (*show)(struct kobject *kobj, struct kobj_attribute *attr,..) Each subclass of kobject should provide their own function with the same signature but more specific types, eg struct device uses: ssize_t (*show)(struct device *dev, struct device_attribute *attr,..) In this case the existing signature is: ssize_t (*show)(struct kobject *kobj, struct device *dev,..) Where kobj is a 'struct mdev_type *' and dev is 'mdev_type->parent->dev'. Change the mdev_type related sysfs attribute functions to: ssize_t (*show)(struct mdev_type *mtype, struct mdev_type_attribute *attr,..) In order to restore type safety and match the driver core standard There are no current users of 'attr', but if it is ever needed it would be hard to add in retroactively, so do it now.

2021-04-12vfio/gvt: Make DRM_I915_GVT depend on VFIO_MDEVJason Gunthorpe
At some point there may have been some reason for this weird split in this driver, but today only the VFIO side is actually implemented. However, it got messed up at some point and mdev code was put in gvt.c and is pretending to be "generic" by masquerading as some generic attribute list: static MDEV_TYPE_ATTR_RO(description); But MDEV_TYPE attributes are only usable with mdev_device, nothing else. Ideally all of this would be moved to kvmgt.c, but it is entangled with the rest of the "generic" code in an odd way. Thus put in a kconfig dependency so we don't get randconfig failures when the next patch creates a link time dependency related to the use of MDEV_TYPE.

2021-04-12spi: hisi-sfc-v3xx: drop unnecessary ACPI_PTR and related ifendif protectionYicong Yang
We use ACPI_PTR() and related ifendif protection for the id table. This is unnecessary as the struct acpi_device_id is defined in mod_devicetable.h and doesn't rely on ACPI. The driver doesn't use any ACPI apis, so it can be compiled in the ACPI=n case with no warnings. So remove the ACPI_PTR and related ifendif protection, also replace the header acpi.h with mod_devicetable.h.

2021-04-12io_uring: return back safer resurrectPavel Begunkov
Revert of revert of "io_uring: wait potential ->release() on resurrect", which adds a helper for resurrect not racing completion reinit, as was removed because of a strange bug with no clear root or link to the patch. Was improved, instead of rcu_synchronize(), just wait_for_completion() because we're at 0 refs and it will happen very shortly. Specifically use non-interruptible version to ignore all pending signals that may have ended prior interruptible wait. This reverts commit cb5e1b81304e089ee3ca948db4d29f71902eb575.

Since fuse just passes ioctl args through to/from server, converting to the fileattr API is more involved, than most other filesystems. Both .fileattr_set() and .fileattr_get() need to obtain an open file to operate on. The simplest way is with the following sequence: FUSE_OPEN FUSE_IOCTL FUSE_RELEASE If this turns out to be a performance problem, it could be optimized for the case when there's already a file (any file) open for the inode.

2021-04-12vfs: add fileattr opsMiklos Szeredi
There's a substantial amount of boilerplate in filesystems handling FS_IOC_[GS]ETFLAGS/ FS_IOC_FS[GS]ETXATTR ioctls. Also due to userspace buffers being involved in the ioctl API this is difficult to stack, as shown by overlayfs issues related to these ioctls. Introduce a new internal API named "fileattr" (fsxattr can be confused with xattr, xflags is inappropriate, since this is more than just flags). There's significant overlap between flags and xflags and this API handles the conversions automatically, so filesystems may choose which one to use. In ->fileattr_get() a hint is provided to the filesystem whether flags or xattr are being requested by userspace, but in this series this hint is ignored by all filesystems, since generating all the attributes is cheap. If a filesystem doesn't implemement the fileattr API, just fall back to f_op->ioctl(). When all filesystems are converted, the fallback can be removed. 32bit compat ioctls are now handled by the generic code as well. Signed-off-by: Miklos Szeredi <mszeredi@redhat.com>
