Set .cmd_size in the SCSI host template such that the SCSI core makes struct scsi_cmnd and struct ufshcd_lrb adjacent. Convert the cmd->lrbp and lrbp->cmd memory loads into pointer offset calculations. Remove the data structure members that became superfluous, namely ufshcd_lrb.cmd and ufs_hba.lrb. Since ufshcd_lrb.cmd is removed, this pointer cannot be used anymore to test whether or not a command is a SCSI command. Introduce a new function for this purpose, namely ufshcd_is_scsi_cmd().

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
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.
