Currently fscrypt_zeroout_range() issues and waits on a bio for each block it writes, which makes it very slow. Optimize it to write up to 16 pages at a time instead. Also add a function comment, and improve reliability by allowing the allocations of the bio and the first ciphertext page to wait on the corresponding mempools.
