Hi All,
I am looking to understand I/O path in linux kernel. Here is following things I have tried to understand it,
- try to understand vfs_write
- then move into fs specific write call
- I thought then after the call goes to I/O scheduler.
- then low-level device driver eg. SCSI, ide
- these drivers read/write sectors.
These are above I/O path I understood at a very high level. Please correct me if somewhere I misunderstood.
I want to get an understanding of how blocks get read and write from a disk. Please suggest me something that will help me to understand and visualize data path in linux kernel.
