+Subject: [PATCH 03/15] crypto: drop mask=CRYPTO_ALG_ASYNC from 'cipher' tfm
+ allocations
+
+'cipher' algorithms (single block ciphers) are always synchronous, so
+passing CRYPTO_ALG_ASYNC in the mask to crypto_alloc_cipher() has no
+effect.  Many users therefore already don't pass it, but some still do.
+This inconsistency can cause confusion, especially since the way the
+'mask' argument works is somewhat counterintuitive.
+
+Thus, just remove the unneeded CRYPTO_ALG_ASYNC flags.
+
+This patch shouldn't change any actual behavior.
