From 91124ac61216ed29405d96a29ec914624b196a79 Mon Sep 17 00:00:00 2001 From: Dave Jiang Date: Tue, 10 Mar 2020 10:51:09 -0700 Subject: dmaengine: idxd: remove global token limit check The global token_limit is not tied to group tokens_reserved and tokens_allowed parameters. Remove the check in order to allow independent configuration.
