As I understand it, for the contents of a directory to be monitored using a kqueue, it must be open (at least O_EVTONLY). Therefore, given that the mds process detects whenever any file on the entire filesystem is written, it seems doubtful that it uses kqueue. Can anyone tell me how it works? Or could anyone recommend an efficient method for determining when a file in a given directory or any of its subdirectories changes, for a potentially large number of subdirectories?
