SubjectRe: [PATCH] scsi: bfa: bfad_attr.c: Optimization of the Code
From
Hi

Several have remarked in the other patch for strncpy I posted. That
there is a strlcpy that works exactly as one would like to strncpy was
done :)
And the return value is like for snprintf, but quite a lot faster!

So I submit patches based with it instead, and did a couple more
exchanges of snprintf to strlcpy.



Best regards
Rickard Strandqvist
