Hi all, Some of you may know that David Howells is working on getting a new system call fsinfo() merged into the Linux kernel. This system call will provide access to information about mounted mounts without having to read and parse file based mount tables such as /proc/self/mountinfo, etc. Essentially all mounts have an id and one can get the id of a mount by it's path and then use that to obtain a large range of information about it. The information can include a list of mounts within the mount which can be used to traverse a tree of mounts or the id used to lookup information on an individual mount without the need to traverse a file based mount table. I'd like to update libmount to use the fsinfo() system call because I believe using file based methods to get mount information introduces significant overhead that can be avoided. Because the fsinfo() system call provides a very different way to get information about mounts, and having looked at the current code, I'm wondering what will be the best way to go about it. Any suggestions about the way this could best be done, given that the existing methods must still work, will be very much appreciated. Ian
