mm/khugepaged: add tracepoint to collapse_file()
"mm_khugepaged_collapse_file" for capturing is_shmem.
Currently, is_shmem is not being captured. Capturing is_shmem is useful
as it can indicate if tmpfs is being used as a backing store instead of
persistent storage. Add the tracepoint in collapse_file() named
"mm_khugepaged_collapse_file" for capturing is_shmem.
[gautammenghani201@gmail.com: swap is_shmem and addr to save space, per Steven Rostedt]
