dm crypt: rename crypt_setkey_allcpus to crypt_setkey (671ea6b4) · Commits · 戴 / test

In the past, dm-crypt used per-cpu crypto context. This has been removed in the kernel 3.15 and the crypto context is shared between all cpus. This patch renames the function crypt_setkey_allcpus to crypt_setkey, because there is really no activity that is done for all cpus. Signed-off-by:
