Subject: [PATCH] virfile: fix cast-align error
RHEL-7.7: https://bugzilla.redhat.com/show_bug.cgi?id=1632711
RHEL-8.0: https://bugzilla.redhat.com/show_bug.cgi?id=1634782
RHEL-7.6.z: https://bugzilla.redhat.com/show_bug.cgi?id=1635705
On s390x the struct member f_type of statsfs is hard coded to 'unsigned
int'. Change virFileIsSharedFixFUSE() to take a 'long long int' and use
a temporary to avoid pointer-casting.
This fixes the following error:
../../src/util/virfile.c:3578:38: error: cast increases required alignment of target type [-Werror=cast-align]
virFileIsSharedFixFUSE(path, (long *) &sb.f_type);
