Are you sure non-fsynced changes are are guaranteed to be visible on block cache level?

Can the syscall filter fake a success of the syscall return value? Correctly written applications check fsync() return value and forward the error. -- Petr _______________________________________________ devel mailing list -- devel@lists.fedoraproject.org To unsubscribe send an email to devel-le...@lists.fedoraproject.org Fedora Code of Conduct: https://getfedora.org/code-of-conduct.html List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@lists.fedoraproject.org/message/UHF75E2SAMZEYFEMHHH265HRRXFPG4PV/
