[PATCH 16/35] staging: lustre: llite: support SELinux context labelling

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Andrew Wellington <andrew.wellington@xxxxxxxxxx>

SELinux contexts are applied by the kernel if mount options are
not binary. As we don't use any binary mount options in Lustre,
remove the binary mount option flag.
