Subject: [PATCH v2] Add missing attributes to EFI variable attribute print out from sysfs
Date: Fri, 13 Jul 2012 11:42:16 -0600 [thread overview]
Message-ID: <20120713174216.GA10445@hp.com> (raw)
Some of the EFI variable attributes are missing from print out from
/sys/firmware/efi/vars/*/attributes. This patch adds those in. It also
updates code to use pre-defined constants for masking current value
of attributes.
