From: Arnd Bergmann <a...@arndb.de>
Building with 'make W=1' shows a harmless -Wempty-body warning:
fs/jbd2/recovery.c: In function 'fc_do_one_pass':
fs/jbd2/recovery.c:267:75: error: suggest braces around empty body in an 'if'
statement [-Werror=empty-body]
267 | jbd_debug(3, "Fast commit replay failed, err = %d\n",
err);
|
^
Change the empty dprintk() macros to no_printk(), which avoids this
warning and adds format string checking.
