Full_Name: Salvador Ortiz Version: 24 OS: Linux URL: ftp://ftp.msg.com.mx/pub/varios/0001-In-mdb_env_copy-retry-open-if-O_DIRECT-fails.patch Submission from: (NULL) (187.162.45.111)

If the OS defines O_DIRECT mdb_env_copy unconditionally uses it, but according to open(2): "Some file systems may not implement the flag and open() will fail with EINVAL if it is used."

In this cases mdb_env_copy should retry without the flag.

The attached patch implements that.
