In landlock_restrict_sibling_threads(), when the calling thread is interrupted while waiting for sibling threads to prepare, it executes a recovery path. Previously, this path included a wait_for_completion() call on all_prepared to prevent a Use-After-Free of the local shared_ctx. However, this wait is redundant. Exiting the main do-while loop already leads to a bottom cleanup section that unconditionally waits for all_finished. Therefore, replacing the wait with a simple break is safe, prevents UAF, and correctly unblocks the remaining task_works. Clean up the error path by breaking the loop and updating the surrounding comments to accurately reflect the state machine.
