Change in vdsm[master]: Remove block size validation from blockSD instatiation.
by ewarszaw＠redhat.com
Eduardo has uploaded a new change for review.
Change subject: Remove block size validation from blockSD instatiation.
......................................................................
Remove block size validation from blockSD instatiation.
This check is unnecessary at this point since vdsm will
fail before if blocks are not 512 sized.
Bug-Url: https://bugzilla.redhat.com/show_bug.cgi?id=955993
