@shuangpeng-kernel kernel-patches-daemon
block: clear ia_ranges on sysfs registration failure
487b7d8 
disk_register_independent_access_ranges() clears disk->ia_ranges when
creating the top-level kobject fails. However, if adding one of the range
kobjects fails, the cleanup drops the final reference to iars and frees it
while disk->ia_ranges still points at it.

A concurrent disk revalidation can wait for q->sysfs_lock and then call
disk_unregister_independent_access_ranges(), which dereferences the stale
pointer after registration releases the mutex.

Clear disk->ia_ranges before dropping the kobject references on the child
registration error path, matching the top-level error handling.
