Date: Fri, 11 Dec 2009 19:57:10 -0500 From: "H Hartley Sweeten" <hartleys@...ionengravers.com> To: "kernel list" <linux-kernel@...r.kernel.org> Subject: Question: drivers/misc/hdpuftrs Hello all, Are the drivers in drivers/misc/hdpuftrs dead? I can't locate anywhere to enable CONFIG_HDPU_FEATURES. Also, both hdpu_cpustate.c and hdpu_nexus.c register as platform drivers but I can't find any users in the mainline tree. Both drivers seem kind of... ugly... hdpu_cpustate.c does a lock_kernel() in the open file_operation. Then does a spin_lock() when checking if the open is O_EXCL. I'm no expert on locking but the lock_kernel() seems unnecessary.
