From d7375ab324971e7acbea9f02a0269ae7348f4147 Mon Sep 17 00:00:00 2001 From: NeilBrown Date: Mon, 26 Jun 2006 00:27:43 -0700 Subject: [PATCH] [PATCH] md/bitmap: fix online removal of file-backed bitmaps When "mdadm --grow /dev/mdX --bitmap=none" is used to remove a filebacked bitmap, the bitmap was disconnected from the array, but the file wasn't closed (until the array was stopped). The file also wasn't closed if adding the bitmap file failed.
