From f99027ab63bee0cbbde549ff663aef8b1c1944b5 Mon Sep 17 00:00:00 2001 From: Miklos Szeredi Date: Wed, 16 Jan 2019 10:27:59 +0100 Subject: fuse: decrement NR_WRITEBACK_TEMP on the right page commit a2ebba824106dabe79937a9f29a875f837e1b6d4 upstream. NR_WRITEBACK_TEMP is accounted on the temporary page in the request, not the page cache page.
