Subject: [IPSEC]: Move linux/crypto.h inclusion out of net/xfrm.h
X-Git-Tag: v2.6.19-rc1~1297^2~56
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=9409f38a0c8773c04bff8dda8c552d7ea013d956;p=linux-2.6

[IPSEC]: Move linux/crypto.h inclusion out of net/xfrm.h

The header file linux/crypto.h is only needed by a few files so including
it in net/xfrm.h (which is included by half of the networking stack) is a
waste.  This patch moves it out of net/xfrm.h and into the specific header
files that actually need it.
