161         help
162           This option determines the default caching mode for the kernel.
163 
164           Write-Back caching mode involves the all reads and writes causing
165           the affected cacheline to be read into the cache first before being
166           operated upon. Memory is not then updated by a write until the cache
167           is filled and a cacheline needs to be displaced from the cache to
168           make room. Only at that point is it written back.
169 
170           Write-Behind caching is similar to Write-Back caching, except that a
171           write won't fetch a cacheline into the cache if there isn't already
172           one there; it will write directly to memory instead.
173 
174           Write-Through caching only fetches cachelines from memory on a
175           read. Writes always get written directly to memory. If the affected
176           cacheline is also in cache, it will be updated too.
177 
178           The final option is to turn of caching entirely.
179 
180           Note that not all CPUs support Write-Behind caching. If the CPU on
181           which the kernel is running doesn't, it'll fall back to Write-Back
182           caching.
