Subject: [PATCH 6/8] io_uring/rsrc: zero node's rsrc data on alloc
Date: Tue, 11 Apr 2023 12:06:06 +0100	[thread overview]
Message-ID: <09bd03cedc8da8a7974c5e6e4bf0489fd16593ab.1681210788.git.asml.silence@gmail.com> (raw)
In-Reply-To: <[email protected]>

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.
