File system for database write-ahead log under Linux
===

I'm looking for a custom file system that would allow me to perform fastest fsync calls so I can put my application's write ahead log there under Linux.

For me the file system should be simplest a single file that represents the image of the disk that I can write/read and call fsync for.

I know that Oracle sometimes uses its own file system to put the journal on to make it fastest.

I assume that somebody had solved this problem before...
