 IMPORTANT: Because some of the blocks have to process entire
 T2 frames, the shared memory requirement will be greater than
-the Linux default. The size of shared memory can be increased
-with the following shell command:
+the Linux default on older kernels. The size of shared memory
+can be increased with the following shell command:
 
 sudo sysctl kernel.shmmax=1073741824
