commit: 0cd9c6494ee5c19aef085152bc37f3a4e774a9e1 From: Darren Hart <[email protected]> Date: Thu, 14 Apr 2011 15:41:57 -0700 Subject: [PATCH] futex: Set FLAGS_HAS_TIMEOUT during futex_wait restart setup
The FLAGS_HAS_TIMEOUT flag was not getting set, causing the restart_block to restart futex_wait() without a timeout after a signal. Commit b41277dc7a18ee332d in 2.6.38 introduced the regression by accidentally removing the the FLAGS_HAS_TIMEOUT assignment from futex_wait() during the setup of the restart block. Restore the originaly behavior.
