From: Leon Romanovsky <[email protected]> Once GCOV fails to duplicate information, the following error is printed: gcov: could not save data for '/home/leonro/src/kernel/drivers/infiniband/hw/mlx5/std_types.gcda' (out of memory)
In the event of out-of-memory such prints are seen for almost every kernel file, so instead of spamming dmesg, we print the first failure and inform the user that future prints are suppressed.
