recent changes of utils/mount cause a regression mount fail:
|
|
|
fc3648 |
https://bugzilla.redhat.com/show_bug.cgi?id=1415024
|
|
|
fc3648 |
can not reproduce it on x86_64(gcc on x86_64 might do struct
|
|
|
fc3648 |
initialize by default, I'm not sure). but it can be reproduced
|
|
|
fc3648 |
always on platform ppc64le aarch64.
