In http://lkml.kernel.org/r/CA+G9fYuDWGZx50UpD+WcsDeHX9vi3hpksvBAWbMgRZadb0Pkww@mail.gmail.com you have said that none of the added tracing output has triggered. Does this still hold? Because I still have a hard time to understand how those three patches could have the observed effects. -- Michal Hocko SUSE Labs _______________________________________________ Linux-f2fs-devel mailing list Linux-f2fs-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/linux-f2fs-devel
