Subject: [PATCH v3 0/3] tracing: Fix the parser when processing strings w/ or w/o terminated '\0'

From: Changbin Du <changbin.du@...el.com>

I found there are some problems in the tracing parser when I investiage the root
cause of issues mentioned in below patch.
https://patchwork.kernel.org/patch/10132953/

This serials can fix them.

v3: Polish commit msg from Steven Rostedt.
v2:
  - Drop 1 old patch and add a new one.
  - Stop parsing when '\0' found.

Changbin Du (3):
  tracing: detect the string termination character when parsing user
    input string
  tracing: clear parser->idx if parser gets nothing
  tracing: make sure the parsed string always terminates with '\0'
