Subject: [PATCH v2 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.
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'
