mmc_block.ko is not included into initrd on kernel 6.1 #2102

Current code in modules.d/90kernel-modules/module-setup.sh looks strange. It assumes that mmc block devices related drivers are always needed, even in hostonly mode, and that =drivers/mmc/ are needed only on embeded hardware (if I understood correctly). |

If run If run it for 6.1: |

Voila, it happened because of commit torvalds/linux@6f8191f "block: simplify disk shutdown" (kernels 6.0+). It says: "Rename blk_cleanup_disk to blk_mq_destroy_queue". I will prepare a quick fix for dracut. |

Commit 6f8191fdf41 ("block: simplify disk shutdown") in Linux kernels 6.0 and above
renamed blk_cleanup_disk to blk_mq_destroy_queue. Adapt code to handle both cases.
Because of the kernel module mmc_block.ko was not included into initrd on kernel 6.1:
dracut-install: No symbol or path match for '/lib/modules/6.1.0-generic-0.rc7.1rosa2021.1-x86_64//kernel/drivers/mmc/core/mmc_block.ko.zs
while on kernel 5.15 it was included:
dracut-install: Handling /lib/modules/5.15.79-generic-1rosa2021.1-x86_64//kernel/drivers/mmc/core/mmc_block.ko.zst
dracut-install: Module mmc_block: symbol blk_cleanup_queue matched inclusion filter
It made booting OS from root on /dev/mmcblk* impossible.
Just adding blk_mq_destroy_queue was not enough to make mmc_block.ko to be included into initrd
(maybe because call of blk_cleanup_disk() was removed and call of blk_mq_destroy_queue() was not added) into it.
So also adding blk_mq_alloc_request.

Kernel module mmc_block.ko is not included into initrd on kernel 6.1-rc7 (
/lib/modules/6.1.0-generic-0.rc7.1rosa2021.1-x86_64/kernel/drivers/mmc/core/mmc_block.ko.zst), but is included on kernel 5.15 (/lib/modules/5.15.77-generic-1rosa2021.1-x86_64/kernel/drivers/mmc/core/mmc_block.ko.zst). This makes booting from root on /dev/mmcblk* impossible with 6.1.I have not understood yet why this happens, but it seems that its inclusion is rather indirect on x86_64 and is done by
_blockfuncs=<...>|mmc_add_host|<...>inmodules.d/90kernel-modules. However I do not see that this function would have been moved between kernels 5.15 and 6.1, it is indrivers/mmc/core/host.cin both kernels.Hardware information gathered on kernel 5.15: https://linux-hardware.org/?probe=3f6ebcde0a
Dracut version is at commit 5eb736, it is not very easy to try a newer dracut, I don't see any relevant changes since that time.
libkmod is v30.
