### Comments for ChangeSet When starting an array fails, we have to tear it down, but in some circumstances (particularly autostart_array) the reference count will be 3, so do_md_stop will fail. With this patch we only worry about the number of users is the array has been fully started. ----------- Diffstat output ------------ ./drivers/md/md.c | 11 +++++------ 1 files changed, 5 insertions(+), 6 deletions(-) diff ./drivers/md/md.c~current~ ./drivers/md/md.c
