commit 30cd85dd6edc86ea8d8589efb813f1fad41ef233 upstream.
fence referencing was out of balance. It was not taking any ref to the fence at creating time, but it was putting a reference when freeing the sync file.
This patch fixes the balancing issue by getting a reference for the fence when creating the sync_file.
