commit e629295bd60abf4da1db85b82819ca6a4f6c1e79 upstream.
When hvs is released, there is a possibility that vsk->trans may not be initialized to NULL, which could lead to a dangling pointer. This issue is resolved by initializing vsk->trans to NULL.

------------------
From: "Liam R. Howlett" Liam.Howlett@Oracle.com
The mmap_region() function tries to install a new vma, which requires a pre-allocation for the maple tree write due to the complex locking scenarios involved.
Recent efforts to simplify the error recovery required the relocation of the preallocation of the maple tree nodes (via vma_iter_prealloc() calling mas_preallocate()) higher in the function.
The relocation of the preallocation meant that, if there was a file associated with the vma and the driver call (mmap_file()) modified the vma flags, then a new merge of the new vma with existing vmas is attempted.
During the attempt to merge the existing vma with the new vma, the vma iterator is used - the same iterator that would be used for the next write attempt to the tree. In the event of needing a further allocation and if the new allocations fails, the vma iterator (and contained maple state) will cleaned up, including freeing all previous allocations and will be reset internally.
Upon returning to the __mmap_region() function, the error is available in the vma_merge_struct and can be used to detect the -ENOMEM status.
Hitting an -ENOMEM scenario after the driver callback leaves the system in a state that undoing the mapping is worse than continuing by dipping into the reserve.
A preallocation should be performed in the case of an -ENOMEM and the allocations were lost during the failure scenario. The __GFP_NOFAIL flag is used in the allocation to ensure the allocation succeeds after implicitly telling the driver that the mapping was happening.
The range is already set in the vma_iter_store() call below, so it is not necessary and is dropped.
