File	Description
components/dfs/dfs_v2/filesystems/procfs/proc_net.c	Wrapped route_show in conditional compilation for LWIP_ROUTE
components/dfs/Kconfig	Updated defaults for procfs, tmpfs, and mqueue under RT_USING_SMART

[Copilot]

[nitpick] Consider adding a comment explaining that the route_show function is conditionally compiled based on the LWIP_ROUTE flag to clarify its dependency for future maintainers.

[Copilot]

[nitpick] Update for RT_USING_DFS_PROCFS default is appropriate; however, add an inline comment explaining that enabling procfs by default under smart is intentional to improve maintainability.

[Copilot]

[nitpick] For clarity, consider including a comment that details why TMPFS (and similarly MQUEUE on line 213) is conditionally enabled when using smart configurations.
