From mboxrd@z Thu Jan 1 00:00:00 1970 From: Geert Uytterhoeven Subject: [PATCH] drivers/input/ff-core.c needs Date: Tue, 1 Jul 2008 13:55:25 +0200 (CEST) Message-ID: Mime-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Return-path: Sender: linux-kernel-owner@vger.kernel.org To: Linus Torvalds , Andrew Morton , Dmitry Torokhov Cc: linux-input@vger.kernel.org, Linux Kernel Development , Linux/m68k List-Id: linux-input@vger.kernel.org commit 656acd2bbc4ce7f224de499ee255698701396c48 Author: Dmitry Torokhov Date: Thu Jun 26 11:30:02 2008 -0400 Input: fix locking in force-feedback core The newly added event_lock spinlock in the input core disallows sleeping and therefore using mutexes in event handlers. Convert force-feedback core to rely on event_lock instead of mutex to protect slots allocated for fore-feedback effects. The original mutex is still used to serialize uploading and erasing of effects. causes the following regression on m68k: | linux/drivers/input/ff-core.c: In function 'input_ff_upload': | linux/drivers/input/ff-core.c:172: error: dereferencing pointer to incomplete type | linux/drivers/input/ff-core.c: In function 'erase_effect': | linux/drivers/input/ff-core.c:197: error: dereferencing pointer to incomplete type | linux/drivers/input/ff-core.c:204: error: dereferencing pointer to incomplete type | make[4]: *** [drivers/input/ff-core.o] Error 1 As the incomplete type is `struct task_struct', including fixes it.
