[Qemu-devel] [PATCH v14 3/5] linux-user: Fix flock structure for MIPS O64 ABI

[Aleksandar Markovic]

From: Aleksandar Markovic <address@hidden>

Only MIPS O32 and N32 have special (different than other
architectures) definition of structure flock in kernel.

Bring flock definition for MIPS O64 ABI to the correct state,
which is currently different than the most common definition,
and it should be the same.
