| |
__xa_store() and xa_store() document that the functions can fail, and that the return code can be an xa_err() encoded error code.
xa_store_bh() and xa_store_irq() do not document that the functions can fail and that they can also return xa_err() encoded error codes.
Thus: Update the documentation.
