[Gluster-devel] Qemu segfaults with recent git

[M. Mohan Kumar]

I tried booting a guest image hosted in GlusterFS volume with Bharata's QEMU
patches with recent glusterfs git tree (commit id:
b10eea2c44272bf491b670466430f4a6d1ac364b)

But I get segfault when QEMU tries to do glfs_init.

I will try to get more information

Here is the backtrace
