Hi,
It seems that there is a mistake in the implementation of
int blkcipher_walk_done(struct blkcipher_desc *desc,
struct blkcipher_walk *walk, int err)
blkcipher_walk_virt() will call crypto_kmap() to map page.
But in the case then err argument is < 0 and we cannot continue then
blkcipher_walk_done() will not
unmap the page.
What do you think?
