fs/ext4/crypto.c: In function 'ext4_encrypted_zeroout':
fs/ext4/crypto.c:459:24: error: 'struct bio' has no member named 'bi_error'
    if ((err == 0) && bio->bi_error)

Various architectures are affected.

Culprit is 'ext4 crypto: fix bugs in ext4_encrypted_zeroout()'.
Guess it either needs a backport or more patches.

Copying Ted.
