Subject: Display number of credits available
From: Steve French <smfrench@xxxxxxxxx>
commit 9742805d6b1bfb45d7f267648c34fb5bcd347397 upstream.
In debugging smb3, it is useful to display the number
of credits available, so we can see when the server has not granted
sufficient operations for the client to make progress, or alternatively
the client has requested too many credits (as we saw in a recent bug)
so we can compare with the number of credits the server thinks
we have.
Add a /proc/fs/cifs/DebugData line to display the client view
on how many credits are available.
