Subject: xt_ACCOUNT: call free_pages(x,2)
X-Git-Tag: v2.10~6
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=f89f10bbe99fcb87646f20ad3345401ee0a67f65;p=thirdparty%2Fxtables-addons.git

xt_ACCOUNT: call free_pages(x,2)

Below is the patch with the *rest* of the free_page(X) calls changed
to free_pages(X, 2). xt_ACCOUNT should always allocate memory in page
pairs. And always *free* memory in page pairs.
