      slub: fix check_bytes() for slub debugging · ef62fb32
      Akinobu Mita 提交于
      The check_bytes() function is used by slub debugging.  It returns a pointer
      to the first unmatching byte for a character in the given memory area.
      
      If the character for matching byte is greater than 0x80, check_bytes()
      doesn't work.  Becuase 64-bit pattern is generated as below.
      
      	value64 = value | value << 8 | value << 16 | value << 24;
      	value64 = value64 | value64 << 32;
      
      The integer promotions are performed and sign-extended as the type of value
      is u8.  The upper 32 bits of value64 is 0xffffffff in the first line, and
      the second line has no effect.
      
      This fixes the 64-bit pattern generation.

      slub: Fix full list corruption if debugging is on · 6fbabb20
      Christoph Lameter 提交于
      When a slab is freed by __slab_free() and the slab can only contain a
      single object ever then it was full (and therefore not on the partial
      lists but on the full list in the debug case) before we reached
      slab_empty.
      
      This caused the following full list corruption when SLUB debugging was enabled:
