[parted-devel] [PATCH v2 2/4] libparted/dasd: update and improve fdasd functions

Wed Oct 26 02:22:47 UTC 2016
Update the fdasd_anchor_t data structure and the fdasd_cleanup()
function. Also correct vtoc_changed and vlabel_changed accounting
because they are important to rewrite vtoc to save the changes.
