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.
