From: Manas <manas18244@xxxxxxxxxxx> syzbot has pointed to a possible null pointer dereference in pfnmap_lockdep_assert. vm_file member of vm_area_struct is being dereferenced without any checks. This fix assigns mapping only if vm_file is not NULL.
I also edited the commit message (and cover letter) slightly to tell about the newer fix, instead of the v1 fix of returning. I hope this is okay. -- Manas
