virtio-9p: fix build on !CONFIG_UTIMENSAT
This patch introduce a fallback mechanism for old systems that do not
support utimensat(). This fix build failure with following warnings:
hw/virtio-9p-local.c: In function 'local_utimensat':
hw/virtio-9p-local.c:479: warning: implicit declaration of function 'utimensat'
hw/virtio-9p-local.c:479: warning: nested extern declaration of 'utimensat'
and:
hw/virtio-9p.c: In function 'v9fs_setattr_post_chmod':
hw/virtio-9p.c:1410: error: 'UTIME_NOW' undeclared (first use in this function)
hw/virtio-9p.c:1410: error: (Each undeclared identifier is reported only once
hw/virtio-9p.c:1410: error: for each function it appears in.)
hw/virtio-9p.c:1413: error: 'UTIME_OMIT' undeclared (first use in this function)
hw/virtio-9p.c: In function 'v9fs_wstat_post_chmod':
hw/virtio-9p.c:2905: error: 'UTIME_OMIT' undeclared (first use in this function)
[NOTE: At this time virtio-9p is only user of utimensat(), and is available
only when host is linux and CONFIG_VIRTFS is defined. So there are
no similar warning for win32. Please provide a wrapper for win32 in
oslib-win32.c if new user really requires it.]
v5:
- Allow fallback on runtime
- Move qemu_utimensat() to oslib-posix.c
- Rebased on latest qemu.git
v4:
- Use tv_now.tv_usec
v3:
- Use better alternative handling for UTIME_NOW/OMIT
- Move qemu_utimensat() to cutils.c
V2:
- Introduce qemu_utimensat()
