    rhashtable: Drop gfp_flags arg in insert/remove functions · 6eba8224

    Reallocation is only required for shrinking and expanding and both rely
    on a mutex for synchronization and callers of rhashtable_init() are in
    non atomic context. Therefore, no reason to continue passing allocation
    hints through the API.
    
    Instead, use GFP_KERNEL and add __GFP_NOWARN | __GFP_NORETRY to allow
    for silent fall back to vzalloc() without the OOM killer jumping in as
    pointed out by Eric Dumazet and Eric W. Biederman.
