strscpy() and the hazards of improved interfaces

Back in the distant past (May 2015), LWN looked at a couple of efforts to provide improved string-handling primitives to the kernel. One of those two was recently merged, while the other has run into trouble; both cases highlight a fundamental concern Linus has about this type of kernel patch. The end result is that it is possible to evolve the kernel toward safer interfaces, but attempts to do so as a series of mass changes will probably not end well.
