[PATCH v2] fs/9p: remove unnecessary extern keywords from function prototypes

[Baran Arda]

Hello Dominique,

Thank you for your feedback. In this second version, I have removed the 'extern' keywords only from function prototypes.

I understand this is a minor cleanup, but it is my first contribution to the Linux kernel and I am excited to learn the process. I appreciate your time and effort in reviewing this.

Best regards,
Baran Arda

fs/9p: remove unnecessary extern keywords from function prototypes

Remove explicit extern keywords from function prototypes in 9p
header files. This cleans up the code in accordance with the
kernel coding style.

v2:
- Restored 'extern' keywords for variables as requested by maintainers.
- Only modified function prototypes in this version.
