Subject: [PATCH] Unwire set/get_robust_list
Date: Mon, 04 Sep 2006 21:27:26 +0200 [thread overview]
Message-ID: <jeodtvfn4x.fsf@sykes.suse.de> (raw)
The syscalls set/get_robust_list must not be wired up until
futex_atomic_cmpxchg_inatomic is implemented. Otherwise the kernel will
hang in handle_futex_death.
