If anyone has any objections, please let me know. ------------------ From: Eddie Lin commit 2fae94ee14f7fea11d3f95e10383a87c01d21518 upstream. The 'ctx_idr' is initialized but never destroyed when the channel context is freed, leading to a memory leak. Add idr_destroy() to properly clean up the IDR resources.
