[PATCH 6/8] xfs: merge xlog_commit_record with xlog_write_done()

[Christoph Hellwig <hch@xxxxxx>]

From: Dave Chinner <dchinner@xxxxxxxxxx>

xlog_write_done() is just a thin wrapper around
xlog_commit_record(), so they can be merged together easily. Convert
all the xlog_commit_record() callers to use xlog_write_done() and
merge the implementations.
