We just don't write them out. Because right now the only thing
that writes out dirty pages is memory pressure. "sync()",
"fsync()" and "fdatasync()" will happily ignore dirty pages
completely. The thing that made me overlook that simple thing in
testing was that I was testing the new VM stuff under heavy VM
load - to shake out any bugs.
Does this mean anyone using test13-pre4 should also expect to see
data not being flushed on shutdown?
I'm not seeing data loss (or it's not obvious if I am) but wonder if
I should make a application to run before halt to allocate and walk
all available memory as an interim?
