os: always check if client is local when connection is accepted
Backported from X.org: commit 2d67ada3c4079a11c52024a9c3d4138becca5171 Author: Pauli Nieminen <ext-pauli.nieminen@nokia.com> Date: Thu Dec 30 19:19:43 2010 +0200 os: always check if client is local when connection is accepted LocalClient is used for all DRI2 requests that makes it frequently called function. Querying if connection is local or not takes 10-15us (on ARM) depending on malloc speed.
