2010-12-02virtio-9p: fix build on !CONFIG_UTIMENSATHidetoshi Seto
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() Acked-by: Chris Wright <chrisw@sous-sol.org> Acked-by: M.

2010-10-30Consolidate oom_check() functionsJes Sorensen
This consolidates the duplicated oom_check() functions, as well as splitting them into OS dependant versions to avoid the #ifdef grossness that was present in the old osdep.c version. Signed-off-by: Jes Sorensen <Jes.Sorensen@redhat.com> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

2010-10-30Move QEMU OS dependant library functions to OS specific filesJes Sorensen
This moves library functions used by both QEMU and the QEMU tools, such as qemu-img, qemu-nbd etc. from osdep.c to oslib-{posix,win32}.c In addition it introduces oslib-obj.y to the Makefile set to be included by the various targets, instead of relying on these library functions magically getting included via block-obj-y.
