From 0069fc6b1cf28de3a3890ed7c87a5b8ab79ca528 Mon Sep 17 00:00:00 2001 From: Jens Axboe Date: Fri, 1 Nov 2019 12:44:40 -0600 Subject: [PATCH] io_uring: remove io_uring_add_to_prev() trace event This internal logic was killed with the conversion to io-wq, so we no longer have a need for this particular trace. Kill it.
