[dm-devel] [PATCH 0/3] HP HSV200 update

Hi Christophe,

this patchset implements a new field 'revision' for the hardware table, 
which is filled with the 'revision' field from the SCSI Inquiry. The 
reason for this is that HP switched the behaviour during a firmware 
update (ie from using START_STOP_UNIT to ALUA). And to support this 
properly we'll have to match against the 'revision' field, too.

In doing so I've found a bug in load_config(). Currently, we're loading
the default hardware table with comparing via regex. However, as the 
default table also contains regexp we'll end up comparing _two_ regexps,
the outcome of which is a quite peculiar to say the least. We should 
rather be using a simple string match to avoid this pitfall.

So, this patchset does
- Correct load_config() to compare entries via string match
- Implements matching against the revision field
- Updates the hardware table for HP HSV200 support.

Cheers,

Hannes
