I've looked at the kernel code and there is no defined value for this length (this is a pointer to a string), but it seems the length of the longest string is 14 [1]. So 4096 seems really overkill. Laurent [1] grep -rh -A3 "struct file_system_type " . |grep "\.name" |sed -n 's/[^"]*"\([^"]*\)".*/\1/p'|while read name; do echo $name|wc -c; done|sort -n|tail -1
