    mm: replace all open encodings for NUMA_NO_NODE · 98fa15f3
    Anshuman Khandual 提交于
    Patch series "Replace all open encodings for NUMA_NO_NODE", v3.
    
    All these places for replacement were found by running the following
    grep patterns on the entire kernel code.  Please let me know if this
    might have missed some instances.  This might also have replaced some
    false positives.  I will appreciate suggestions, inputs and review.
    
    1. git grep "nid == -1"
    2. git grep "node == -1"
    3. git grep "nid = -1"
    4. git grep "node = -1"
    
    This patch (of 2):
    
    At present there are multiple places where invalid node number is
    encoded as -1.  Even though implicitly understood it is always better to
    have macros in there.  Replace these open encodings for an invalid node
    number with the global macro NUMA_NO_NODE.  This helps remove NUMA
    related assumptions like 'invalid node' from various places redirecting
    them to a common definition.
