+rpcdebug \- set and clear NFS and RPC kernel debug flags

+.SH DESCRIPTION
+The \fBrpcdebug\fP command allows an administrator to set and clear
+the Linux kernel's NFS client and server debug flags.  Setting these
+flags causes the kernel to emit messages to the system log in response
+to NFS activity; this is typically useful when debugging NFS problems.
+.PP
+The first form in the synopsis can be used to list all available
+debug flags.  The second form shows the currently set debug flags
+for the given module.  The third form sets one or more flags, and
+the fourth form clears one or more flags.
+.PP
+The value \fBall\fP may be used to set or clear all the flags for
+the given module.
