As is the case with ramback. Just echo 1 >/proc/driver/ramback/<name>. That is why I keep recommending that a ramback setup be replicated or mirrored, which people in this thread keep glossing over. When replicated or mirrored, you still get the microsecond-level transaction times, and you get the safety too. Then there is a big class of applications where the data on the ramdisk can be reconstructed, it is just a pain and reduces uptime. These are potential ramback users, and in fact I will be one of those, using it on my kernel hacking partition. There will be a whole bunch of patches from me that are SSD oriented, over time. The fact is, enterprise scale ramdisks are here now, while enterprise scale flash is not. Getting close, but not here. And flash does not approach the write performance of RAM, not now and probably not ever. Daniel --
