sdong e3a82bb934 PosixRandomAccessFile::MultiRead() to use I/O uring if supported (#5881) ... Summary: Right now, PosixRandomAccessFile::MultiRead() executes read requests in parallel. In this PR, it leverages I/O Uring library to run it in parallel, even when page cache is enabled. This function will fall back if the kernel version doesn't support it. Pull Request resolved: https://github.com/facebook/rocksdb/pull/5881 Test Plan: Run the unit test on a kernel version supporting it and make sure all tests pass, and run a unit test on kernel version supporting it and see it pass. Before merging, will also run stress test and see it passes. Differential Revision: D17742266 fbshipit-source-id: e05699c925ac04fdb42379456a4e23e4ebcb803a		2019-12-07 20:55:52 -08:00
