Summary: [NB: this is a prerequisite for the /tmp-abuse-fixing patch] This avoids spurious test failure on Linux systems like Fedora for which /tmp is a tmpfs file system. On a devtmpfs file system, ioctl(fd, FS_IOC_GETVERSION, &version) returns -1 with errno == ENOTTTY, indicating that that ioctl is not supported on such a file system. Do not let this cause test failures, e.g., where env_test would assert that file->GetUniqueId(...) > 0. Before this change, ./env_test would fail these three tests on a fedora rawhide system: [ FAILED ] 3 tests, listed below: [ FAILED ] EnvPosixTest.RandomAccessUniqueID [ FAILED ] EnvPosixTest.RandomAccessUniqueIDConcurrent [ FAILED ] EnvPosixTest.RandomAccessUniqueIDDeletes 3 FAILED TESTS The fix: When support for that ioctl is lacking, skip each affected test. Could be improved by noting which sub-tests are being skipped. Test Plan: run these on F21 and note that they now pass.

RocksDB: A Persistent Key-Value Store for Flash and RAM Storage
RocksDB is developed and maintained by Facebook Database Engineering Team. It is built on earlier work on LevelDB by Sanjay Ghemawat (sanjay@google.com) and Jeff Dean (jeff@google.com)
This code is a library that forms the core building block for a fast key value server, especially suited for storing data on flash drives. It has a Log-Structured-Merge-Database (LSM) design with flexible tradeoffs between Write-Amplification-Factor (WAF), Read-Amplification-Factor (RAF) and Space-Amplification-Factor (SAF). It has multi-threaded compactions, making it specially suitable for storing multiple terabytes of data in a single database.

See the github wiki for more explanation.
The public interface is in include/. Callers should not include or
rely on the details of any other header files in this package. Those
internal APIs may be changed without warning.
