new_tape_buffer() is never called in atomic context. new_tape_buffer() is only called by st_probe(), which is only set as ".probe" in struct scsi_driver. Despite never getting called from atomic context, new_tape_buffer() calls kzalloc() with GFP_ATOMIC, which does not sleep for allocation. GFP_ATOMIC is not necessary and can be replaced with GFP_KERNEL, which can sleep and improve the possibility of sucessful allocation. This is found by a static analysis tool named DCNS written by myself. And I also manually check it. Signed-off-by: Jia-Ju Bai <baijiaju1990@gmail.com> Signed-off-by: Martin K.
