Good point. (It would be possible to analyze whole stack by slave/holders relations, but I agree it's too complex and probably too fragile.) > > Anyway, if you still want to read userspace mount options than I can > > add something like: > > > > mnt_inotify_mtab_add_watch() > > mnt_inotify_mtab_rm_watch() > > mnt_inotify_mtab_changed() > > > > to hide all the paths and private mtab/utab stuff. > Maybe something more like what journal client code does here: > > mnt_mtab_get_fd() -> epoll fd > mnt_mtab_get_events() -> EPOLLIN|EPOLLPRI > mnt_mtab_process() -> information what changed Hmm.. utab is optional and very often does not exist, and library uses rename(2) to do atomic update of the file. This is reason why Chris have used inotify for /run/mount directory (and Lennart asked for inotify API). I have doubts you can use epoll to monitor directories, epoll is about I/O monitoring.
