[Drbd-dev] [PATCH] drbdmeta: also show negotiated size in sectors

[Iustin Pop]

Currently drbdmeta shows the last agreed size in "nice" units, e.g.
100GB. But this is imprecise, as the shifting of cfg->md.la_sect loses
the low-order bits.

This small patch adds a new line to the output of drbdmeta that shows
the exact negotiated size in sectors (for both new and initialized
devices), such that the output of drbdmeta can be parsed.

 This is against drbd 8.3 but should apply (and I would be grateful if this is
 applied) to 8.0 too.

 thanks,
 iustin
