Subject: [PATCH v5 0/1] tracing: Fix an event field filter issue

Hi,

Here is the 5th version of series to fix the tracing event filter
because of __attribute__.

The previous version is here;
https://lore.kernel.org/all/175333238644.2267214.1835493691667067597.stgit@mhiramat.tok.corp.google.com/

This version fixes some code according to Steve's comments.
Especially, to avoid strstr(), run sanitize_field_type() first. This
also, simplifies the error handling. If failed to allocate memory,
return immediately, but if there is any wrong string etc, it just
skips the field.

This removes the __attribute__ from the event format type string,
which can cause issues with parsing (detecting the string type).

Thank you,
