[PATCH 00/21] libmultipath: checkers overhaul

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

 



Hi Christophe,

This series starts with a few minor fixes and then attempts
an overhaul of the checker code.

First, there's a block of patches to get rid of the "message"
char array in struct checker, replacing it with an integer.
This topic had been touched in recent discussion between Ben
and myself.

The next larger block fixes problems with checkers that try
to check unsupported devices. It's an interesting experience
to configure wrong checkers for the existing devices and see
what happens. With these patches, paths won't be falsely
teared down any more in such situations.

The last patch cleans up the checker data structure by splitting
it into a "checker class" and the path "checker instance".

There's more work to do in this area, but this is a start.

Regards,
Martin
