[PATCH 20/35] multipathd: move uxsock_trigger() to uxlsnr.c

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

 



From: Martin Wilck <mwilck@xxxxxxxx>

uxsock_trigger() really belongs into cli.c. I suppose that way back in
the past there were strong reasons to call this function via a
pointer. I don't think these reasons are valid any more. Moving
the function to cli.c allows restructuring the code.

No functional changes.
