From 60e5bb7844ec75a2f54ea76d8ceec5c79172ce7e Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Tue, 13 Mar 2018 23:15:28 -0700 Subject: xfs: merge _xfs_log_force and xfs_log_force Switch to a single interface for flushing the whole log, which gives consistent trace point coverage, and removes the unused log_flushed argument for the previous _xfs_log_force callers.
