Subject: [PATCH] virfile: fix cast-align error
|

On s390x the struct member f_type of statsfs is hard coded to 'unsigned
|
|
|
a5a3f0 |
int'. Change virFileIsSharedFixFUSE() to take a 'long long int' and use
|
|
|
a5a3f0 |
a temporary to avoid pointer-casting.
|
|
|
a5a3f0 |
|
|
|
a5a3f0 |
This fixes the following error:
|
|
|
a5a3f0 |
../../src/util/virfile.c:3578:38: error: cast increases required alignment of target type [-Werror=cast-align]
|
|
|
a5a3f0 |
virFileIsSharedFixFUSE(path, (long *) &sb.f_type);
