X-Git-Tag: omap-for-v4.2/fixes-rc1^2~106^2~53
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=a6d403ac96893cb5c5812c2d75de082795f02e5f;p=pandora-kernel.git

netconsole: remove unnecessary netconsole_target_get/out() from write_msg()

write_msg() grabs target_list_lock and walks target_list invoking
netpool_send_udp() on each target.  Curiously, it protects each iteration
with netconsole_target_get/put() even though it never releases
target_list_lock which protects all the members.

While this doesn't harm anything, it doesn't serve any purpose either.
The items on the list can't go away while target_list_lock is held.
Remove the unnecessary get/put pair.
