4.4-stable review patch. If anyone has any objections, please let me know.

[for older kernels only, lustre has been removed from upstream]
When someone writes: strncpy(dest, source, sizeof(source)); they really are just doing the same thing as: strcpy(dest, source); but somehow they feel better because they are now using the "safe" version of the string functions. Cargo-cult programming at its finest...
gcc-8 rightfully warns you about doing foolish things like this. Now that the stable kernels are all starting to be built using gcc-8, let's get rid of this warning so that we do not have to gaze at this horror.
To dropt the warning, just convert the code to using strcpy() so that if someone really wants to audit this code and find all of the obvious problems, it will be easier to do so.
