Subject: mm/huge_memory.c: rename shadowed local
X-Git-Tag: microblaze-v6.16~78^2~194
X-Git-Url: http://git.monstr.eu/?a=commitdiff_plain;h=1fc10653552c17b9f336a81014f20465e664a2ec;p=linux-2.6-microblaze.git

mm/huge_memory.c: rename shadowed local

split_huge_pages_write() has a lccal `buf' which shadows incoming arg
`buf'.  Reviewer confusion resulted.  Rename the inner local to `tok_buf'.
