From 13c223962eac16f161cf9b6355209774c609af28 Mon Sep 17 00:00:00 2001 From: Pavel Begunkov Date: Tue, 11 Apr 2023 12:06:06 +0100 Subject: io_uring/rsrc: zero node's rsrc data on alloc struct io_rsrc_node::rsrc_data field is initialised on rsrc removal and shouldn't be used before that, still let's play safe and zero the field on alloc.
