EVFILT_FS has existed in FreeBSD since 2004. EVFILT_FS is triggered only when mounting or unmounting a filesystem. (FreeBSD later added some NFS events in addition to mount/unmount, but this commit doesn't apply those) The patch needs to be reviewed as I've only read kern/kern_event.c today to briefly understand the mechanism. https://leaf.dragonflybsd.org/~tkusumi/diff/0001-sys-kern-Add-EVFILT_FS.patch sample userspace code https://leaf.dragonflybsd.org/~tkusumi/diff/kqueue1.c -- [root@]~# gcc -Wall -g ./kqueue1.c -o ./kqueue1 [root@]~# ./kqueue1 timeout timeout timeout timeout timeout timeout filesystem event filter=-10 mount timeout timeout filesystem event filter=-10 unmount timeout timeout filesystem event filter=-10 mount filesystem event filter=-10 unmount timeout timeout timeout ^C -- You have received this notification because you have either subscribed to it, or are involved in it.
