Pull fscrypt updates from Eric Biggers:
"Simplify how fscrypt uses the crypto API, resulting in some
significant performance improvements:
- Drop the incomplete and problematic support for asynchronous
algorithms. These drivers are bug-prone, and it turns out they are
actually much slower than the CPU-based code as well.
- Allocate crypto requests on the stack instead of the heap. This
improves encryption and decryption performance, especially for
filenames. This also eliminates a point of failure during I/O"
