Anders Roxell 3c8a15f222 vdpa: Fix IDR memory leak in VDUSE module exit ... [ Upstream commit d9ea58b5dc ] Add missing idr_destroy() call in vduse_exit() to properly free the vduse_idr radix tree nodes. Without this, module load/unload cycles leak 576-byte radix tree node allocations, detectable by kmemleak as: unreferenced object (size 576): backtrace: [<ffffffff81234567>] radix_tree_node_alloc+0xa0/0xf0 [<ffffffff81234568>] idr_get_free+0x128/0x280 The vduse_idr is initialized via DEFINE_IDR() at line 136 and used throughout the VDUSE (vDPA Device in Userspace) driver for device ID management. The fix follows the documented pattern in lib/idr.c and matches the cleanup approach used by other drivers. This leak was discovered through comprehensive module testing with cumulative kmemleak detection across 10 load/unload iterations per module.
