Hello Neil,Jes,
Question about the patch
" md/raid1: Avoid raid1 resync getting stuck"
Is this patch relevant for kernel 3.18? In Linus's tree I don't see
this patch being tagged for stable[1].
Thanks,
Alex.

md/raid1: Avoid raid1 resync getting stuck
close_sync() needs to set conf->next_resync to a large, but safe value
below MaxSector and use it to determine whether or not to set
start_next_window in wait_barrier()
Solution suggested by Neil Brown.
