[Cluster-devel] [PATCH 2/2] gfs2_edit savemeta: Fix use of uninitialized 'blk'

[Andrew Price]

Fixes
  "savemeta.c:737:14: warning: ‘blk’ may be used uninitialized in this function"

blk is never actually used uninitialized here but the compiler can't
reason it out, so make it explicit to silence the warning.
