From 9eae8655f9cd2eeed99fb7a0d2bb22816c17e497 Mon Sep 17 00:00:00 2001 From: Pavel Begunkov Date: Tue, 4 Apr 2023 13:39:54 +0100 Subject: io_uring/rsrc: cache struct io_rsrc_node Add allocation cache for struct io_rsrc_node, it's always allocated and put under ->uring_lock, so it doesn't need any extra synchronisation around caches.
