Hello,

This patch series adds the "discard" option to block by extending the swap
entries of fstab config with the discard parameter that provides full control
over the discard feature.
swapon is another entry point for swap activation, so it gets an extra flag -d.
The implementation is inspired by busybox.
I've been runninng with these patches applied since the post time, with
no issues.
[ 28.419614] Adding 204796k swap on /dev/dm-3. Priority:-2 extents:1
across:204796k SSDsc
swapon on a rotational drive ignores the discard flag:
# swapon -d /dev/vg0/swap1
# echo $?
0
# dmesg | grep 'Adding.*swap' | tail -n1
[610560.700332] Adding 102396k swap on /dev/vg0/swap1. Priority:-3
extents:1 across:102396k
Is there any chance to get them reviewed and applied?
