Subject: [PATCH 14/26] libxfs: convert libxfs_log_clear to use uncached buffers
Date: Fri, 28 Feb 2020 15:37:48 -0800	[thread overview]
Message-ID: <158293306846.1549542.6988917301256455028.stgit@magnolia> (raw)
In-Reply-To: <158293297395.1549542.18143701542461010748.stgit@magnolia>

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

Convert the log clearing function to use uncached buffers like
everything else, instead of using the raw buffer get/put functions.
This will eventually enable us to hide them more effectively.
