So I'd prefer reuse mm/zbud.c and mm/zswap.c for a generic memory compression solution. Which means in that case, zcache in staging = mm/zswap.c + mm/zcache.c + mm/zbud.c. But I'm not sure if there are any existing users of zcache in staging, if not I can delete zcache from staging in my next version of this mm/zcache.c series. > greg k-h > > -- > To unsubscribe, send a message with 'unsubscribe linux-mm' in > the body to majordomo@kvack.org.
