Subject: Re: [PATCH 1/2] fs/efs/inode.c: follow style guide
Hi Amy,
What mail client did you use?
It is breaking (splitting) long lines into shorter lines and that
makes it not possible to apply the patch cleanly.
You can see this problem below or on the web in an email archive.
Possibly Documentation/process/email-clients.rst can help you.
