Summary
scsi: target: iblock: Fix wrong PR ops NULL check for PREEMPT/RELEASE
Details

In the Linux kernel, the following vulnerability has been resolved:

scsi: target: iblock: Fix wrong PR ops NULL check for PREEMPT/RELEASE

In the iblockexecuteprout() function, PROPREEMPT, PROPREEMPTANDABORT, and PRORELEASE all perform callback capability checks through ops->pr_clear. The error check allows unimplemented hooks to pass through the gate, resulting dereferencing a NULL function pointer.

Check whether the hooks that need to be called are supported.
