If I try to mount it from Linux,ýusing userfoo and the correct password all is well. If I try with a bad password or with some other username (userbar), it fails with "Permission denied" as expected. If I try to mount as username = administrator, and give the correct administrator password, I would also expect "Permission denied", but I see "Cannot allocate memory" instead.

Looks like the commit 0b8f18e3 assumed that cifs_get_inode_info() and
friends fail only due to memory allocation error when the inode is NULL
which is not the case if CIFSSMBQPathInfo() fails and returns an error.
Fix this by propagating the actual error code back.
