ext4: fast commit fixes This patch series adds several documentation and code-only (no on disk format changes) fixes for the fast commit code. I verified that there were no regressions introduced by this patch series in xfstests auto and log groups in fast_commit and 4k configurations. Thanks Jan for suggesting most of the fixes.
