From daaadb3e9453ab89c2e113a2d1df8e19e30944cc Mon Sep 17 00:00:00 2001 From: Omar Sandoval Date: Thu, 4 May 2017 00:31:34 -0700 Subject: mq-deadline: add debugfs attributes Expose the fifo lists, cached next requests, batching state, and dispatch list. It'd also be possible to add the sorted lists, but there aren't already seq_file helpers for rbtrees.
