I ran across systemd/src/basic/path-util.c:fd_is_mount_point() the other day, and the contortions it goes through made me wonder if we should also add mnt_id and/or an is_mountpoint boolean--it's annoying to have to do name_to_handle_at() (not supported on all filesystems) just to get mnt_id. (Looking at it now I see it falls back on reading mount id from /proc/self/fdinfo/<fd>. Maybe that's good enough. May depend on whether there's a potential user that doesn't want to assume access to /proc?) --b. -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
