From de31947931e71362bd4bf69f68e8dc5d162e56a6 Mon Sep 17 00:00:00 2001 From: "Darrick J. Wong" Date: Sun, 1 Mar 2020 12:34:10 -0500 Subject: [PATCH] libxfs: convert libxfs_log_clear to use uncached buffers 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. Signed-off-by: Darrick J.
