+struct bdev_handle { + struct block_device *bdev; + void *holder; +};Please explain in the patch description why a holder pointer is introduced in struct bdev_handle and how it relates to the bd_holder pointer in struct block_device. Is one of the purposes of this patch series perhaps to add support for multiple holders per block device?That is all in patch 0/32. Why repeat it?
This cover letter: https://lore.kernel.org/linux-block/20230629165206.383-1-jack@suse.cz/T/#t (local)? The word "holder" doesn't even occur in that cover letter so how could the answer to my question be present in the cover letter? Bart.
