Subject: [RHEL7.5 PATCH 087/169] Grow_continue_command: ensure 'content'
|
|
|
b7f731 |
is properly initialised.
|
|
|
b7f731 |
|
|
|
b7f731 |
Grow_continue_command() call verify_reshape_position(), which assumes
|
|
|
b7f731 |
that info->sys_name is initialised.
|
|
|
b7f731 |
'info' in verify_reshape_position() is 'content' in Grow_continue_command().
|
|
|
b7f731 |
|
|
|
b7f731 |
In the st->ss->external != 0 branch of that function, sysfs_init() is called
|
|
|
b7f731 |
to initialize content->sys_name.
|
|
|
b7f731 |
In the st->ss->external == 0 branch, ->sys_name is not initialized so
|
|
|
b7f731 |
verify_reshape_position() will not do the right thing.
