    fs/ocfs2/dlm: Use GFP_ATOMIC under spin_lock · a48a982a
    David Sterba authored
    coccinelle check scripts/coccinelle/locks/call_kern.cocci found that
    in fs/ocfs2/dlm/dlmdomain.c an allocation with GFP_KERNEL is done
    with locks held:
    
    dlm_query_region_handler
      spin_lock(dlm_domain_lock)
        dlm_match_regions
          kmalloc(GFP_KERNEL)
    
    Change it to GFP_ATOMIC.
