Merged following change from MySQL 5.6 to MariaDB 10.1 XtraDB including the test case: https://github.com/mysql/mysql-server/commit/520aedfe INNODB: "DATA DIRECTORY" OPTION OF CREATE TABLE FAILS WITH PWRITE() OS ERROR 22 Fix for version mysql-5.6 PROBLEM ======== For version mysql-5.6.27 onwards InnoDB fails to create a table with explicit 'data directory' option when Innodb_flush_method is set to O_DIRECT.While creating link file we get a a pwrite error 22 due to the alignment restrictions imposed by O_DIRECT flag which is being set for the link file created. FIX === Fixed the above issue by making use of file IO functions while creating the link file that wouldn't let the O_DIRECT flag restrictions arise.
