commit efb36504c51c39b2d5900d21bfbf0f73c8e94a2e Author: Alexander Motin <[email protected]> AuthorDate: 2022-01-28 16:09:30 +0000 Commit: Alexander Motin <[email protected]> CommitDate: 2022-02-11 00:50:45 +0000 graid: Set G_CF_DIRECT_SEND for task consumer. Unlike normal consumers all taste consumer I/O is synchronous, done with g_read_data() and without any locks held. It makes no sense to delegate I/O submission to g_down thread. This should remove number of context switches during disk retaste.
