Linus Torvalds d6a326d694 tracing: Remove second argument of __assign_str() ... The __assign_str() macro logic of the TRACE_EVENT() macro was optimized so that it no longer needs the second argument. The __assign_str() is always matched with __string() field that takes a field name and the source for that field: __string(field, source) The TRACE_EVENT() macro logic will save off the source value and then use that value to copy into the ring buffer via the __assign_str(). Before commit c1fa617cae ("tracing: Rework __assign_str() and __string() to not duplicate getting the string"), the __assign_str() needed the second argument which would perform the same logic as the __string() source parameter did. Not only would this add overhead, but it was error prone as if the __assign_str() source produced something different, it may not have allocated enough for the string in the ring buffer (as the __string() source was used to determine how much to allocate) Now that the __assign_str() just uses the same string that was used in __string() it no longer needs the source parameter. It can now be removed. -----BEGIN PGP SIGNATURE----- iIkEABYIADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCZk9RMBQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6qur+AP9jbSYaGhzZdJ7a3HGA8M4l6JNju8nC GcX1JpJT4z1qvgD3RkoNvP87etDAUAqmbVhVWnUHCY/vTqr9uB/gqmG6Ag== =Y+6f -----END PGP SIGNATURE----- Merge tag 'trace-assign-str-v6.10' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull tracing cleanup from Steven Rostedt: "Remove second argument of __assign_str() The __assign_str() macro logic of the TRACE_EVENT() macro was optimized so that it no longer needs the second argument.
