Do you ever wish that you could monitor cgroup creation / removal race-free with fanotify? Now you can! Any kernfs works!

Linux v6.6-rc1 is out and it contains my commit:

* https://github.com/torvalds/linux/commit/0ce7c12e88cf

Example usage in Go:

* https://github.com/cloudflare/ebpf_exporter/pull/244

All you do is ask for events from a mount and then read them in a loop. No need to re-arm watches like with inotify.

The patch is trivial and can be easily backported if you want it in an older kernel.

I just released #fatrace 0.17.0, with a nice contribution to fix zfs monitoring, and some bug fixes. Already uploaded to #debian.

Released earlier this month, kernel 5.16 is full of great features, including two that had been in development for some time by our kernel team: the new #futex syscall & the new #fanotify event! Here's a look at our contributions: https://col.la/lk516 #futex2 #embedded

@bjarni prefer #fanotify to #inotify for that, it now has a filestystem-broad mode.
