From: Dave Hansen dave.hansen@linux.intel.com Date: Fri, 10 Nov 2017 16:12:31 -0800 Subject: x86/pkeys/selftests: Rename 'si_pkey' to 'siginfo_pkey'
From: Dave Hansen dave.hansen@linux.intel.com
commit 91c49c2deb96ffc3c461eaae70219d89224076b7 upstream.
'si_pkey' is now #defined to be the name of the new siginfo field that protection keys uses. Rename it not to conflict.
