From d8d4b20df48287a7e9e37f706c410b13bc0438cf Mon Sep 17 00:00:00 2001 From: Matt Fleming Date: Tue, 14 Feb 2012 11:40:57 +0000 Subject: [PATCH] OpenRISC: Use set_current_blocked() and block_sigmask() As described in e6fa16ab ("signal: sigprocmask() should do retarget_shared_pending()") the modification of current->blocked is incorrect as we need to check whether the signal we're about to block is pending in the shared queue. Also, use the new helper function introduced in commit 5e6292c0f28f ("signal: add block_sigmask() for adding sigmask to current->blocked") which centralises the code for updating current->blocked after successfully delivering a signal and reduces the amount of duplicate code across architectures. In the past some architectures got this code wrong, so using this helper function should stop that from happening again.
