[dm-devel] [PATCH] multipath compilation fixes

[Hannes Reinecke <hare suse de>]

Hi Christophe,

dm_mapname returns a strdup()ed string, which does not really
qualify as const. This patchs corrects it.

Cheers,

Hannes

[devmapper] Compilation fixes

As we're returning a strdup()ed string from dm_mapname() it hardly
qualifies as 'const'.
