Hello everybody. I am modifying ufshcd driver: https://elixir.bootlin.com/linux/v3.8/source/drivers/scsi/ufs/ufshcd.c I do a read of a file on ext4 filesystem and want to obtain the file's inode. But it seems that there are no structures contatin any references to inode at this level of abstraction. I looked into scsi_cmd structure and all the structures it references to. Also I used ftrace to find on which level of abstraction inode disappear but without any luck. Could you please say to me where I could find the lowest level where inode is still present and the best way how to pass it throughout linux io stack to the ufshcd driver? Frankly speaking I need not struct inode as a whole but just its number, so using reserved or unused fields of existing structures is appropriate. -- Kind regards, Roman
