commit 3e55ef26d49a900782d2c2bb2c03470faed6ec9d
Author: Jan Lindström <jan.lindstrom@mariadb.com>
Date: Wed May 20 13:35:51 2015 +0300

MDEV-8173: InnoDB; Failing assertion: crypt_data->type == 1

Make sure that when we publish the crypt_data we access the
memory cache of the tablespace crypt_data. Make sure that
crypt_data is stored whenever it is really needed.

All this is not yet enough in my opinion because:

sql/encryption.cc has DBUG_ASSERT(scheme->type == 1) i.e.
crypt_data->type == CRYPT_SCHEME_1

However, for InnoDB point of view we have global crypt_data
for every tablespace. When we change variables on crypt_data
we take mutex. However, when we use crypt_data for
encryption/decryption we use pointer to this global
structure and no mutex to protect against changes on
crypt_data.

Tablespace encryption starts in fil_crypt_start_encrypting_space
from crypt_data that has crypt_data->type = CRYPT_SCHEME_UNENCRYPTED
and later we write page 0 CRYPT_SCHEME_1 and finally whe publish
that to memory cache.
