Subject: [PATCH io_uring-7.1 v2 2/5] io_uring/zcrx: don't use mark0 for allocating xarray
Date: Wed, 25 Mar 2026 13:09:19 +0000	[thread overview]
Message-ID: <b5be2425e187942277ecebec034a2294794bffcb.1774444007.git.asml.silence@gmail.com> (raw)
In-Reply-To: <cover.1774444007.git.asml.silence@gmail.com>

XA_MARK_0 is not compatible with xarray allocating entries, use
XA_MARK_1.

Fixes: fda90d43f4fac ("io_uring/zcrx: return back two step unregistration")
