Subject: [PATCH] libmount: don't use nosuid,noexec,nodev for cifs user=foo
mount -t cifs //127.0.0.1/users /mnt/smb -o user=root,password=linux
is incorrectly translated to
mount.cifs -o noexec,nosuid,nodev,user=root,password=linux ...
The command mount(8) should be sensitive to "user" (without "=<name>")
only. The correct cifs command line is:
mount.cifs -o user=root,password=linux
