swapon: add -o <list> for compatibility with mount
The new option allows to specify swap options by fstab compatible
string. The concept is the same as for mount(8).
swapon -o pri=1,discard=pages,nofail /dev/sda2
The advantage is that tools (like systmed) that parses fstab can call
swapon without translation from fstab options to swapon(8) command
line options.
