Second update: .swap_activate is not implemented in the linux kernel
for exfat and the commit causes EINVAL only for swap allocation. That
is caused by bmap() due to the generic swap activation.

So instead of working around the issue, we probably should have a feature
in the kernel along with fallocate() support in exfat.

Probably a kernel bug/missing feature.
