[ Upstream commit cc4332afb5631b0e9d2ce5699b7f4b7caf743526 ]

The function Device::from_raw() increments a refcount by a call to bindings::get_device(ptr). This can be confused because usually from_raw() functions don't increment a refcount. Hence, rename Device::from_raw() to avoid confuion with other "from_raw" semantics.

The new name of function should be "get_device" to be consistent with the function get_device() already exist in .c files.

This function body also changed, because the `into()` will convert the `&'a Device` into `ARef<Device>` and also call `inc_ref` from the `AlwaysRefCounted` trait implemented for Device.

[ Upstream commit 3eb40512530e4f64f819d8e723b6f41695dace5a ]

SMB protocol for native symlinks distinguish between symlink to directory and symlink to file. These two symlink types cannot be exchanged, which means that symlink of file type pointing to directory cannot be resolved at all (and vice-versa).

Windows follows this rule for local filesystems (NTFS) and also for SMB.

Linux SMB client currenly creates all native symlinks of file type. Which means that Windows (and some other SMB clients) cannot resolve symlinks pointing to directory created by Linux SMB client.

As Linux system does not distinguish between directory and file symlinks, its API does not provide enough information for Linux SMB client during creating of native symlinks.

Add some heuristic into the Linux SMB client for choosing the correct symlink type during symlink creation. Check if the symlink target location ends with slash, or last path component is dot or dot-dot, and check if the target location on SMB share exists and is a directory. If at least one condition is truth then create a new SMB symlink of directory type. Otherwise create it as file type symlink.

This change improves interoperability with Windows systems. Windows systems would be able to resolve more SMB symlinks created by Linux SMB client which points to existing directory.

Currently this driver prints this line with what looks like a rogue format specifier when the device is probed: [ 2.840000] eth%d: MVME147 at 0xfffe1800, irq 12, Hardware Address xx:xx:xx:xx:xx:xx

Change the printk() for netdev_info() and move it after the registration has completed so it prints out the name of the interface properly.

[ Upstream commit b983b271662bd6104d429b0fd97af3333ba760bf ]

Disabling preemption in the GRU driver is unnecessary, and clashes with sleeping locks in several code paths. Remove preempt_disable and preempt_enable from the GRU driver.
