Subject: [PATCH] revert "Optimize sys_times for a single thread process"
X-Git-Tag: v2.6.17-rc1~181
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=35f5cad8c4bab94ecc5acdc4055df5ea12dc76f8;p=pandora-kernel.git

[PATCH] revert "Optimize sys_times for a single thread process"

This patch reverts 'CONFIG_SMP && thread_group_empty()' optimization in
sys_times().  The reason is that the next patch breaks memory ordering which
is needed for that optimization.

tasklist_lock in sys_times() will be eliminated completely by further patch.
