From 8c40984eeb8804cffcd28640f427f4fe829243fc Mon Sep 17 00:00:00 2001 From: Su Yue glass.su@suse.com Date: Mon, 8 Apr 2024 16:20:40 +0800 Subject: [PATCH] ocfs2: update inode fsync transaction id in ocfs2_unlink and ocfs2_link
transaction id should be updated in ocfs2_unlink and ocfs2_link. Otherwise, inode link will be wrong after journal replay even fsync was called before power failure: ======================================================================= $ touch testdir/bar $ ln testdir/bar testdir/bar_link $ fsync testdir/bar $ stat -c %h $SCRATCH_MNT/testdir/bar 1 $ stat -c %h $SCRATCH_MNT/testdir/bar 1 =======================================================================
