[Qemu-devel] [PATCH 3/7] linux-user/syscall.c: handle FUTEX_WAIT_BITSET in do_futex |
Date: |
Thu, 7 Mar 2013 10:21:28 +0000 |
From: John Rigby <address@hidden>
Upstream libc has recently changed to start using
FUTEX_WAIT_BITSET instead of FUTEX_WAIT and this
is causing do_futex to return -TARGET_ENOSYS.
Pass bitset in val3 to sys_futex which will be
ignored by kernel for the FUTEX_WAIT case.
