[Cluster-devel] [fsck.gfs2 PATCH 1 of 2] fsck.gfs2: Change duptree structure to have generic flags

[Bob Peterson <rpeterso@redhat.com>]

Hi,

This is part 1 of a 2-patch set for fsck.gfs2.

This patch does not change any functionality. It merely changes the
specialized first_ref_found flag to a flag within a multi-flag var.

Regards,
