Date: Tue, 12 Oct 2021 20:28:37 -0700 From: Qing Wang <wangqing@...o.com> To: Chris Mason <clm@...com>, Josef Bacik <josef@...icpanda.com>, David Sterba <dsterba@...e.com>, linux-btrfs@...r.kernel.org, linux-kernel@...r.kernel.org Cc: Qing Wang <wangqing@...o.com> Subject: [PATCH] btrfs: replace snprintf in show functions with sysfs_emit coccicheck complains about the use of snprintf() in sysfs show functions. Fix the following coccicheck warning: fs/btrfs/sysfs.c:335:8-16: WARNING: use scnprintf or sprintf. Use sysfs_emit instead of scnprintf or sprintf makes more sense.
