maquefel · vinodkoul · commit 5422145d0b74 · 2024-06-11T23:39:26.000+05:30
Fix missing kmem_cache_destroy() for ioat_sed_cache in ioat_exit_module(). Noticed via: ``` modprobe ioatdma rmmod ioatdma modprobe ioatdma debugfs: Directory 'ioat_sed_ent' with parent 'slab' already present! ``` Fixes: c0f28ce ("dmaengine: ioatdma: move all the init routines") Signed-off-by: Nikita Shubin <n.shubin@yadro.com> Acked-by: Dave Jiang <dave.jiang@intel.com> Link: https://lore.kernel.org/r/20240514-ioatdma_fixes-v1-1-2776a0913254@yadro.com Signed-off-by: Vinod Koul <vkoul@kernel.org>
