Comparisons are done in the normal order (if (need > available), not if (available < need)), variables have reduced scope and are renamed for clarity. The only functional change is that if we return -ENAMETOOLONG, we do that without modifying the options[] array. I also added an explanatory comment. The use of one offset to point into three buffers is not obvious. Coverity (in CID#1402354) says that sname might be accessed at bad offset, but I cannot see this happening. We check for available space before writing anything.
