Andrew Kryczka 4bf169f07e Disable readahead when using mmap for reads ... Summary: `ReadaheadRandomAccessFile` had an unwritten assumption, which was that its wrapped file's `Read()` function always copies into the provided scratch buffer. Actually this was not true when the wrapped file was `PosixMmapReadableFile`, whose `Read()` implementation does no copying and instead returns a `Slice` pointing directly into the `mmap`'d memory region. This PR: - prevents `ReadaheadRandomAccessFile` from ever wrapping mmap readable files - adds an assert for the assumption `ReadaheadRandomAccessFile` makes about the wrapped file's use of scratch buffer Closes https://github.com/facebook/rocksdb/pull/3813 Differential Revision: D7891513 Pulled By: ajkr fbshipit-source-id: dc64a55222d6af280c39a1852ee39e9e9d7cde7d		7 years ago
