It has definitely been one of the most +talked about, most used, and most visible features. By +providing a window into kernel objects, their +attributes, and the relationships between them, a lot +of opportunities arise: +\begin{enumerate} +\item to cleanup existing code that +has traditionally used proc, +\item to easily port code +that has traditionally used procfs to export object +attributes, and +\item to integrate new subsystems with +configurable and exportable attributes. +\end{enumerate} + +While sysfs has been a great benefit for a large amount +code in the kernel, it's far from perfect. This talk +will discuss those imperfections, including but not +limited to, the places and situations where it's +cumbersome or inappropriate to use sysfs; how sysfs +suffers from some of the same problems as procfs and +sysctl by making it easy to duplicate code and +propagate bugs; and what the performance impact of +using sysfs is. + +It won't be an unmitigated tomato-throwing session, +though. The purpose of identifying and characterizing +the problems is simply the first step in making it +better. Current developments and plans for the near +future to fix or alleviate the problems will be +described. The pundits will be placated and the critics +pacified in the next few steps towards total +domination. + + -- cgit v1.2.3
