Re: XTS Crypto Not Found In /proc/crypto Even After Compiled for 4.10.1.

[Nathan Royce]

Sure, I went ahead and rebuilt it just using the bare exynos_defconfig
and adding XTS and ECB and no other changes.

No flags were used. No patches were used other than the 2 you
provided. Just the barest of bears, the barest of bones, the barest of
deserts, the barest of hairless cats.

I also wiped out the 4.10.1 modules directory and zImage and dtb
before copying them into place.

I'm sure you could just copy my crypttab and fstab entries that is
shown in my first email.
