[Linux-kernel-mentees] [PATCH v3 2/3] parsing_hacks: Add bool to list of known typedefs

[Jaskaran Singh <jaskaransingh7654321@gmail.com>]

bool is widely used in the Linux kernel. Certain cases of
parsing_hacks.ml would mislabel bool.

Add bool to the list of known typedefs.

Stats of --parse-c on Linux v5.5-rc4 are as follows:

Before:

  nb good = 18956150,  nb passed = 134062 =========> 0.70% passed

After:

  nb good = 18956150,  nb passed = 134073 =========> 0.70% passed

The increase in passed tokens is due to functions in
kernel/trace/trace_kprobe.c using nokprobe_inline. For instances of
nokprobe_inline bool, nokprobe_inline is labeled as a CppMacro.

Examples of this in the --parse-c diff are as follows:

Before:
  passed:bool
  passed:bool
  passed:bool
  passed:bool
  passed:bool

After:
  passed:nokprobe_inline
  passed:nokprobe_inline
  passed:nokprobe_inline
  passed:nokprobe_inline
  passed:nokprobe_inline
  passed:nokprobe_inline
  passed:nokprobe_inline
