+# 1 x DNS resolver
+# 1 x Matter Stack
+# 1 x MQTT / AWS IoT integration
+CONFIG_ZVFS_EVENTFD_MAX=10


The comment explains why CONFIG_ZVFS_EVENTFD_MAX=10 is needed (listing 9 required events), but there's no explanation for why CONFIG_ZVFS_POLL_MAX=12 is set to 12. Consider adding a comment explaining this value's rationale.

Suggested change

CONFIG_ZVFS_EVENTFD_MAX=10

CONFIG_ZVFS_EVENTFD_MAX=10

# Allow polling of all eventfds plus a small margin (e.g. sockets and other FDs)
