    [PATCH] mm: tlb_is_full_mm was obscure · 4d6ddfa9
    Hugh Dickins authored
    tlb_is_full_mm?  What does that mean?  The TLB is full?  No, it means that the
    mm's last user has gone and the whole mm is being torn down.  And it's an
    inline function because sparc64 uses a different (slightly better)
    "tlb_frozen" name for the flag others call "fullmm".
    
    And now the ptep_get_and_clear_full macro used in zap_pte_range refers
    directly to tlb->fullmm, which would be wrong for sparc64.  Rather than
    correct that, I'd prefer to scrap tlb_is_full_mm altogether, and change
    sparc64 to just use the same poor name as everyone else - is that okay?
