-Subject: [PATCH] futex: Add entry point for FUTEX_WAIT_MULTIPLE (opcode 31)
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Add an option to wait on multiple futexes using the old interface, that
-uses opcode 31 through futex() syscall. Do that by just translation the
-old interface to use the new code. This allows old and stable versions
-of Proton to still use fsync in new kernel releases.

-Subject: [PATCH] futex: Add entry point for FUTEX_WAIT_MULTIPLE (opcode 31)
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Add an option to wait on multiple futexes using the old interface, that
-uses opcode 31 through futex() syscall. Do that by just translation the
-old interface to use the new code. This allows old and stable versions
-of Proton to still use fsync in new kernel releases.
