Add atomic writes beta support to 5.5
Add a Fusion I/O / DirectFS-specific doublewrite buffer replacement boolean option: --innodb-
If enabled, this option issues a DFS-specific IOCTL call to enable the atomic write feature. If the underlying FS does not support this IOCTL, server quits. Otherwise doublewrite buffer is disabled, O_DIRECT is enabled for the data files and any writes to the data files then become atomic, i.e. at the application level we don't have to deal with the partial writes.
This feature is considered to be beta quality until we implementing testing infrastructure in Jenkins/MTR.
The implementation is to be adapted from MariaDB:
