[dm-devel] [PATCH dmraid 0/1] pdc metadata bug fix

[NeilBrown]

Hi,
 the follow patch fixes a bug with pdc metadata handling, as described
 in that patch.

 I noted on reading the code that if pdc_read_metadata finds the metadata
 at and address listed in begin_sectors, info->u32 is set to an offset
 from the start of the device, rather than from the end, and then the use
 of info->u32 in setup_rd becomes incorrect.
 I didn't try to fix this as I don't know all the implications of
 a 'begin_sectors' address being used.

Thanks,
NeilBrown
