Subject: [PATCH] Kprobe: multi kprobe posthandler for booster
X-Git-Tag: v2.6.18-rc1~781
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=36721656776f177280ccb50477a02e86e6444292;p=pandora-kernel.git

[PATCH] Kprobe: multi kprobe posthandler for booster

If there are multi kprobes on the same probepoint, there will be one extra
aggr_kprobe on the head of kprobe list.  The aggr_kprobe has
aggr_post_handler/aggr_break_handler whether the other kprobe
post_hander/break_handler is NULL or not.  This patch modifies this, only
when there is one or more kprobe in the list whose post_handler is not
NULL, post_handler of aggr_kprobe will be set as aggr_post_handler.
