From 8f51f38883dcff93f55e132d3d8b1c991e809474 Mon Sep 17 00:00:00 2001 From: Tang Junhui Date: Wed, 6 Sep 2017 14:25:53 +0800 Subject: bcache: do not subtract sectors_to_gc for bypassed IO commit 69daf03adef5f7bc13e0ac86b4b8007df1767aab upstream. Since bypassed IOs use no bucket, so do not subtract sectors_to_gc to trigger gc thread.
