From: Herbert Xu Date: Fri, 18 Nov 2011 02:20:04 +0000 (+0000) Subject: ipv4: Remove all uses of LL_ALLOCATED_SPACE X-Git-Tag: v3.3-rc1~182^2~540 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=660882432909dbe611f1792eda158188065cb9f1;p=pandora-kernel.git ipv4: Remove all uses of LL_ALLOCATED_SPACE ipv4: Remove all uses of LL_ALLOCATED_SPACE The macro LL_ALLOCATED_SPACE was ill-conceived. It applies the alignment to the sum of needed_headroom and needed_tailroom. As the amount that is then reserved for head room is needed_headroom with alignment, this means that the tail room left may be too small. This patch replaces all uses of LL_ALLOCATED_SPACE in net/ipv4 with the macro LL_RESERVED_SPACE and direct reference to needed_tailroom. This also fixes the problem with needed_headroom changing between allocating the skb and reserving the head room. Signed-off-by: Herbert Xu Signed-off-by: David S.
