From c2c17ddbf32bd89c4b5e3eb71068b52c890d07df Mon Sep 17 00:00:00 2001 From: Steve French Date: Fri, 15 Jul 2022 23:45:45 -0500 Subject: [PATCH] cifs: remove some camelCase and also some static build warnings Remove warnings for five global variables. For example: fs/cifs/cifsglob.h:1984:24: warning: symbol 'midCount' was not declared. Should it be static? Also change them from camelCase (e.g. "midCount" to "mid_count") Reviewed-by: Paulo Alcantara (SUSE) Signed-off-by: Steve French --- fs/cifs/cifs_debug.c | 14 +++++++------- fs/cifs/cifsfs.c | 17 ++++++++++++----- fs/cifs/cifsglob.h | 10 +++++----- fs/cifs/connect.c | 2 +- fs/cifs/misc.c | 12 ++++++------ fs/cifs/smb2transport.c | 2 +- fs/cifs/transport.c | 4 ++-- 7 files changed, 34 insertions(+), 27 deletions(-) diff --git a/fs/cifs/cifs_debug.c b/fs/cifs/cifs_debug.c index 97116c1..f5e63df 100644 --- a/fs/cifs/cifs_debug.c +++ b/fs/cifs/cifs_debug.c @@ -514,8 +514,8 @@ static ssize_t cifs_stats_proc_write(struct file *file, #ifdef CONFIG_CIFS_STATS2 int i;
