Unfortunately this broke even attach of the mlx5(4) driver. According to the 'official' Linux kernel documentation, the GFP_KERNEL flag implies sleepable context. mlx5_core uses the passed GFP flag to determine if it is called in the sleepable context, and now even initial load assumes that it cannot perform sleeping ops. See, for instance, second if() statement in the mlx5_fwp_alloc() function.
Oh sorry... Thank you for reporting the issue. I will revisit this change then. Should I revert it in main until there is a solution?
