[PATCH 11/13] populate: adjust rtrmap calculations for rtgroups

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



From: Darrick J. Wong <djwong@xxxxxxxxxx>

Now that we've sharded the realtime volume and created per-group rmap
btrees, we need to adjust downward the size of rtrmapbt records since
the block counts are now 32-bit instead of 64-bit.
