Subject: osdep: Make qemu_madvise() return ENOSYS on unsupported OSes
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=210b7b2b3cdef01a15ebabf02dd1a9d8a51743ba;p=qemu.git

osdep: Make qemu_madvise() return ENOSYS on unsupported OSes

Not every OS is capable of madvise() or posix_madvise() even. In
that case, errno should be set to ENOSYS as it reflects the cause
better.
