CONFIG_SUNRPC_DEBUG_TRACE: RPC: Send dfprintk() output to the trace buffer

General informations

The Linux kernel configuration item CONFIG_SUNRPC_DEBUG_TRACE:

• prompt: RPC: Send dfprintk() output to the trace buffer
• type: bool
• depends on: CONFIG_SUNRPC_DEBUG && CONFIG_TRACING
• defined in net/sunrpc/Kconfig
• found in Linux kernels: 6.18-rc+HEAD

Help text

dprintk() output can be voluminous, which can overwhelm the kernel's logging facility as it must be sent to the console. This option causes dprintk() output to go to the trace buffer instead of the kernel log.

This will cause warnings about trace_printk() being used to be logged at boot time, so say N unless you are debugging a problem with sunrpc-based clients or services.
