[LU-8958] remove code left unused after lloop removal

• Type: Bug
• Resolution: Fixed
• Priority: Minor
• Fix Version/s: Lustre 2.10.1, Lustre 2.11.0
• Severity: 3
• Assignee: James A Simmons
• Reporter: John Hammond

Description

There is a fair amount of easy cleanup that can be done now that lloop has been removed. The LL_MRF_RETURN macros can be removed. Several autoconf defines/checks are no longer referenced:

HAVE_QC_MAKE_REQUEST_FN
HAVE_VOID_MAKE_REQUEST_FN
HAVE_BIO_ENDIO_USES_ONE_ARG
HAVE_REQUEST_QUEUE_UNPLUG_FN
HAVE_BLKDEV_RELEASE_RETURN_INT

ll_iocontrol_register(), ll_iocontrol_unregister(), ll_iocontrol_call(), and the llioc* structures can be removed.

ll_direct_rw_pages() is not longer used outside of llite and should be merged with ll_direct_IO_seg(). struct ll_dio_pages() can be removed.

In sanity.sh the LLOOP and LLITELOOPLOAD variables and the function cleanup_68() are unused.
