Subject: [RFC PATCH v2 06/13] ima: move INVALID_PCR() to ima.h
Date: Sun, 23 Mar 2025 15:09:04 +0100	[thread overview]
Message-ID: <20250323140911.226137-7-nstange@suse.de> (raw)
In-Reply-To: <20250323140911.226137-1-nstange@suse.de>

Make the INVALID_PCR() #define available to other compilation units
by moving it from ima_policy.c to ima.h and renaming it to
IMA_INVALID_PCR() in the course.
