Subject: [PATCH 0/2] tracing: Fix an event field filter issue

Hi,

Here is a series to fix some issues in the tracing event filter.
The first patch removes the __attribute__ from the event format type
string, which can cause issues with parsing (detecting the string
type). The second patch optimizes memory allocation in
__trace_define_field() by only allocating field->type when it
needs to be sanitized.

Thank you,
