From 8c911f3d4c074a17955a1757c9d1d5a9a5209ca5 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Wed, 1 Jul 2020 11:06:21 +0200 Subject: writeback: remove struct bdi_writeback_congested We never set any congested bits in the group writeback instances of it. And for the simpler bdi-wide case a simple scalar field is all that that is needed.
