From 00c2bf85d8febfcfddde63822043462b026134ff Mon Sep 17 00:00:00 2001 From: Nadia Derbey Date: Fri, 25 Jul 2008 01:48:03 -0700 Subject: ipc: get rid of ipc_lock_down() Remove the ipc_lock_down() routines: they used to call idr_find() locklessly (given that the ipc ids lock was already held), so they are not needed anymore.
