From: Steve French Date: Tue, 20 Sep 2016 03:06:35 +0000 (-0500) Subject: Display number of credits available X-Git-Tag: v3.16.40~192 X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=a8c714961c25fcf77a044fb89a00f38e2e8a23f8;p=thirdparty%2Fkernel%2Fstable.git Display number of credits available 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.
