padbad is the current default behaviour.
The difference between skipbad and omitbad is this one:
On a 16K block NAND, if the 1st block of mtd0 is bad, we'll have:

swapon/swapoff: size reduction, cleanup, fixes, improvements
1) real swapon/swapoff handles also devices on the commandline with -a;
2) xstat(device) in swap_enable_disable aborts on error when cycling through
fstab so some devices are not handled;
3) duplicated code for ENABLE_FEATURE_SWAPON_DISCARD and
ENABLE_FEATURE_SWAPON_PRI was moved to functions.
4) silence some error messages with -a;
5) minor cleanups and code refactoring reduced the size as per bloat-check:
6) I also added support for /proc/swaps handling to swapoff:
"When the -a flag is given, swapping is disabled on all known swap devices
and files (as found in /proc/swaps or /etc/fstab)."
So now swapoff first cycles through /proc/swaps and then through fstab
to swapoff all devices.
