X-Git-Tag: v2.6.20-rc1~145^2^2~7^2~9 X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=905eee008b5440e30186ab72c238ec8cb2886f74;p=linux-2.6-omap-h63xx.git [TCP] inet_twdr_hangman: Delete unnecessary memory barrier(). As per Ralf Baechle's observations, the schedule_work() call should give enough of a memory barrier, so the explicit one here is totally unnecessary. Signed-off-by: David S.
