Steve Longerbeam a6eccfac83 gpu: ipu-v3: image-convert: Prevent race between run and unprepare ... [ Upstream commit 819bec35c8 ] Prevent possible race by parallel threads between ipu_image_convert_run() and ipu_image_convert_unprepare(). This involves setting ctx->aborting to true unconditionally so that no new job runs can be queued during unprepare, and holding the ctx->aborting flag until the context is freed. Note that the "normal" ipu_image_convert_abort() case (e.g. not during context unprepare) should clear the ctx->aborting flag after aborting any active run and clearing the context's pending queue. This is because it should be possible to continue to use the conversion context and queue more runs after an abort.
