[Cluster-devel] [PATCH v2 4/4] gfs2: convert to errseq_t based writeback error reporting for fsync

[Jeff Layton]

From: Jeff Layton <jlay...@redhat.com>

This means that we need to export the new file_fdatawait_range symbol.

Also, fix a place where a writeback error might get dropped in the
gfs2_is_jdata case.
