### Comments for ChangeSet This flag was used by multipath to make sure only one superblock was written, as there is only one real device. The relevant test is now more explicitly dependant on multipath, and the flag is gone. ----------- Diffstat output ------------ ./drivers/md/md.c | 10 ++++------ ./include/linux/raid/md_k.h | 1 - 2 files changed, 4 insertions(+), 7 deletions(-)
