lmb: rename to memblock
via following scripts FILES=$(find * -type f | grep -vE 'oprofile|[^K]config') sed -i \ -e 's/lmb/memblock/g' \ -e 's/LMB/MEMBLOCK/g' \ $FILES for N in $(find . -name lmb.[ch]); do M=$(echo $N | sed 's/lmb/memblock/g') mv $N $M done and remove some wrong change like lmbench and dlmb etc. also move memblock.c from lib/ to mm/ Suggested-by: Ingo Molnar <mingo@elte.hu> Acked-by: "H.
