Hi,

Was wondering if there is a way to count the number of times map.ringbuf_reserve() fails for a BPF_RINGBUF_OUTPUT buffer?

This way I can get notified in userspace that I have missed events, and might need to increase the buffer size.

Cheers,

Eelco

Thought I added the #bcc tag but I no longer see it :( So just in case, it's not clear, this is with BCC.
