[Cluster-devel] [GFS2 PATCH 4/4] gfs2: gfs2_ail_empty_gl no log flush on error

[Bob Peterson <rpeterso@redhat.com>]

Before this patch function gfs2_ail_empty_gl called gfs2_log_flush even
in cases where it encountered an error. It should probably skip the log
flush and leave the file system in an inconsistent state, letting a
subsequent withdraw force the journal to be replayed to reestablish
metadata consistency.
