Subject: [PATCH 26/26] libxfs: convert buffer priority get/set macros to functions
Date: Fri, 28 Feb 2020 15:39:03 -0800	[thread overview]
Message-ID: <158293314326.1549542.4350225962633251739.stgit@magnolia> (raw)
In-Reply-To: <158293297395.1549542.18143701542461010748.stgit@magnolia>

From: Darrick J. Wong <darrick.wong@oracle.com>

Convert these shouty macros to proper functions.  We can't make them
static inline functions unless I f the 'libxfs_bcache' reference.
