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. 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 c1fa617caeb0 ("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"
