Subject: [IPSEC]: Make callers of xfrm_lookup to use XFRM_LOOKUP_WAIT
X-Git-Tag: v2.6.25-rc1~1162^2~1115
X-Git-Url: http://www.pilppa.org/gitweb/gitweb.cgi?a=commitdiff_plain;h=bb72845e699d3c84e5f861b51db686107a51dea5;p=linux-2.6-omap-h63xx.git

[IPSEC]: Make callers of xfrm_lookup to use XFRM_LOOKUP_WAIT

This patch converts all callers of xfrm_lookup that used an
explicit value of 1 to indiciate blocking to use the new flag
XFRM_LOOKUP_WAIT.
