6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Wentao Liang <vulab@xxxxxxxxxxx>
commit fb95897b8c60653805aa09daec575ca30983f768 upstream.
In xfs_dax_write_iomap_end(), directly return the result of
xfs_reflink_cancel_cow_range() when !written, ensuring proper
error propagation and improving code robustness.
Fixes: ea6c49b784f0 ("xfs: support CoW in fsdax mode")
