[patch] [SCSI] target: allow release() to be called on NULL pointers

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This is a cleanup and not a bugfix.

container_of() does pointer math and the result of that math can
basically not be NULL here so "se_dev" is non-NULL.

Normally release() type functions accept a NULL parameter.  I don't
think target_core_dev_release() is ever called with a NULL parameter but
it's a cleaner to allow that.

So instead of checking "se_dev", I've changed it to check "item".
