Hi!

Can some one add O_EVTONLY and O_NOATIME to open()?

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=214338 devel/glib20: patch: new kqueue() backend for file monitoring

Without O_NOATIME open() on file/dir always update attributes -> file browsing via sshfs/internet get very slow.
Without O_EVTONLY kqueue() cant monitor dirs/files than locked, also this cause unmount proublems.


IMHO O_NOATIME - easy to add.
