I don't have a strong opinion. The four callers could be changed, but my gut reaction is that it is a much higher priority to add useful dynamic tracepoints (ftrace ie trace-cmd) to cifs to make it easier to debug real customer problems that are currently awkward to debug. By comparison, even ext4 has over 100 dynamic tracepoints, but larger file systems like XFS has 500 (!), and nfs (including SunRPC) has about 100. My guess is that going from our current 28 dynamic trace points (in cifs.ko) to double that (at least) will happen as developers add tracepoints to help them debug real problems (and of course it will help developers working on future problems even more ...) > > On 7 Oct 2018, at 15:59, Steve French <smfrench@xxxxxxxxx> wrote: > > > > Merged into cifs-2.6.git for-next > > > > Made a trivial tab/space correction in the patch (pointed out by > > checkpatch) and then added a trivial followon patch to address a > > comment/style (trivial) > > issue pointed out by checkpatch and to add a little more detailed > > comments about generally when to use each debug function.
