Re: [libvirt] [PATCH v2 0/2] qemu: Fix stalls during live core dump

Version 2: - generalize virFileDirectFd a bit more as suggested by Eric Jiri Denemark (2): util: Generalize virFileDirectFd qemu: Always use iohelper for dumping domain core src/qemu/qemu_driver.c | 45 +++++++++++-------- src/util/virfile.c | 118 +++++++++++++++++++++++++++++------------------- src/util/virfile.h | 21 ++++++--- 3 files changed, 112 insertions(+), 72 deletions(-)
