commit 565ad82c453170009a58431399301dec44b56ad7 Author: Alexander Motin <[email protected]> AuthorDate: 2022-01-28 19:22:41 +0000 Commit: Alexander Motin <[email protected]> CommitDate: 2022-02-11 00:50:46 +0000 glabel: Set G_CF_DIRECT_SEND/RECEIVE for taste consumer. All I/O requests through the taste consumer are synchronous, done with g_read_data() and without any locks held. It makes no sense to delegate the I/O to g_down/g_up threads. This removes many of context switches during disk retaste.
