Subject: [PATCH io_uring-7.1 v3 3/6] io_uring/zcrx: don't use mark0 for allocating xarray
Date: Tue, 31 Mar 2026 22:07:40 +0100 [thread overview]
Message-ID: <f232cfd3c466047d333b474dd2bddd246b6ebb82.1774780198.git.asml.silence@gmail.com> (raw)
In-Reply-To: <cover.1774780198.git.asml.silence@gmail.com>
XA_MARK_0 is not compatible with xarray allocating entries, use
XA_MARK_1.
