Subject: [PATCH] fs/ntfs: remove unused varibles
Date: Sun,  8 Nov 2020 15:38:12 +0800	[thread overview]
Message-ID: <1604821092-54631-1-git-send-email-alex.shi@linux.alibaba.com> (raw)

We actually don't use these varibles, so remove them to avoid gcc warning:
fs/ntfs/file.c:326:14: warning: variable ‘base_ni’ set but not used
[-Wunused-but-set-variable]
fs/ntfs/logfile.c:481:21: warning: variable ‘log_page_mask’ set but not
used [-Wunused-but-set-variable]
