In the filesystem that i am writing, i have various statistics being gathered over time in a central data structure. On linux we expose this structure to userspace through a /proc entry. Is there an equivalent of /proc interface in xnu that can be use to expose arbitrary statistics? Particularly for arbitrary statistics private to your FS that are privately formatted and meaningless to everyone else, you will need to expose them via an fsctl() and query for them. Or you can expose them via an fcntl() after obtaining a file handle for an object known to be on your file system. Or you can expose them in your own namespace; if exposing them in the FS namespace in a procfs is in theory somehow a good idea, exposing the same information in the FS namespace for AbhijitFS is also in theory a good idea.
