Fix subvol del --commit-after to work properly: - SYNC ioctl will be issued even when last delete is failed - SYNC ioctl will be issued on each file system only once in the end To achieve this, each deleted subvol's (parent's) fsid is checked each time. If the fsid is seen for the first time, its fd will be kept in order to issue SYNC ioctl in the end. There already exists get_fsid() in cmds-property.c and seen_fsid which keeps fsid in hush function in cmds-filesystem.c. First three patches make them to common functions and last one is the main part.
