+Subject: [PATCH] io_uring: implement io_uring_enable_rings locally (#1915)
+
+Summary:
+Pull Request resolved: https://github.com/facebook/folly/pull/1915
+
+io_uring_enable_rings was missing from liburing upstream (see https://github.com/axboe/liburing/issues/773) which is breaking the open source build. See https://github.com/facebook/folly/issues/1908
+
+Instead just implement it locally, as it's trivial
