From 08694199477da412baf1852c6d1bf5fedbd40c7e Mon Sep 17 00:00:00 2001 From: Mike Christie Date: Sat, 27 Feb 2021 10:59:56 -0600 Subject: scsi: target: core: Add gfp_t arg to target_cmd_init_cdb() tcm_loop could be used like a normal block device, so we can't use GFP_KERNEL and should use GFP_NOIO. This adds a gfp_t arg to target_cmd_init_cdb() and converts the users. For every driver but loop GFP_KERNEL is kept. This will also be useful in subsequent patches where loop needs to do target_submit_prep() from interrupt context to get a ref to the se_device, and so it will need to use GFP_ATOMIC.
