commit48d83282dbupstream. A regression fix introduced a harmless type mismatch warning: drivers/scsi/bfa/bfad_bsg.c: In function 'bfad_im_bsg_vendor_request': drivers/scsi/bfa/bfad_bsg.c:3137:35: error: initialization of 'struct bfad_im_port_s *' from 'long unsigned int' makes pointer from integer without a cast [-Werror=int-conversion] struct bfad_im_port_s *im_port = shost->hostdata[0]; ^~~~~ drivers/scsi/bfa/bfad_bsg.c: In function 'bfad_im_bsg_els_ct_request': drivers/scsi/bfa/bfad_bsg.c:3353:35: error: initialization of 'struct bfad_im_port_s *' from 'long unsigned int' makes pointer from integer without a cast [-Werror=int-conversion] struct bfad_im_port_s *im_port = shost->hostdata[0]; This changes the code back to shost_priv() once more, but encapsulates it in an inline function to document the rather unusual way of using the private data only as a pointer to the previously allocated structure. I did not try to get rid of the extra indirection level entirely, which would have been rather invasive and required reworking the entire initialization sequence.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
