Adam Simpkins 28f54e71f3 fix compile errors in db/kv_checksum.h (#9173)
Summary:
When defining a template class, the constructor should be specified
simply using the class name; it does not take template arguments.a

Apparently older versions of gcc and clang did not complain about this
syntax, but gcc 11.x and recent versions of clang both complain about
this file.

Pull Request resolved: https://github.com/facebook/rocksdb/pull/9173

Test Plan:
When building with platform010 I got compile errors in this file both
in `mode/dev` (clang) and in `mode/opt-gcc`.  This diff fixes the
compile failures.

RocksDB: A Persistent Key-Value Store for Flash and RAM Storage

CircleCI Status TravisCI Status Appveyor Build status PPC64le Build Status

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 especially suitable for storing multiple terabytes of data in a single database.

Start with example usage here: https://github.com/facebook/rocksdb/tree/main/examples

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.

Design discussions are conducted in https://www.facebook.com/groups/rocksdb.dev/ and https://rocksdb.slack.com/
