   5 //     [PATCH] getting rid of all casts of k[cmz]alloc() calls
   6 //
   7 //     Run this:
   8 //
   9 //         #! /bin/sh
  10 //         for f in $(grep -Erl "\([^\)]*\) *k[cmz]alloc" *) ; do
  11 //           echo "De-casting $f..."
  12 //           perl -pi -e "s/ ?= ?\([^\)]*\) *(k[cmz]alloc) *\(/ = \1\(/" $f
  13 //         done
  14 //
  15 //     And then go through and reinstate those cases where code is
  16 // casting pointers    to non-pointers.
  17 //
  18 //     And then drop a few hunks which conflicted with outstanding work.
