[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



5.15-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Douglas Anderson <dianders@xxxxxxxxxxxx>

[ Upstream commit e2e821095949cde46256034975a90f88626a2a73 ]

The function kdb_position_cursor() takes in a "prompt" parameter but
never uses it. This doesn't _really_ matter since all current callers
of the function pass the same value and it's a global variable, but
it's a bit ugly. Let's clean it up.

Found by code inspection. This patch is expected to functionally be a
no-op.
