![]() In recently sysfs_poll discussion, Neil Brown pointed out /proc/mounts also should be fixed. SUSv3 says "Regular files shall always poll TRUE for reading and writing". see http://www.opengroup.org/onlinepubs/009695399/functions/poll.html Then, mounts_poll()'s default should be "POLLIN | POLLRDNORM". it mean always readable. In addition, event trigger should use "POLLERR | POLLPRI" instead POLLERR. it makes consistent to mdstat_poll() and sysfs_poll(). and, select(2) can handle POLLPRI easily.
