Hi , Thanks for your patience regarding my questions. Because after I had dug (digged) very older posts, I realized many of the older posts already had answers for many of my earlier questions :). After your couple of answers and going through old posts, I have a better understanding of *user land* and *kernel land*.
Now one more point. *Kernel land: * While we are at kernel land, I have a confusion on that. AFAIK in linux kernel, the linux *block layer* is a glue that, on the one hand, allows applications to access diverse storage devices in a uniform way, and on the other hand, provides storage devices and drivers with a single point of entry from all applications. I mean this Linux OS (host) block layer is the most critical part of the I/O hierarchy, as it orchestrates the I/O requests from different applications to the underlying storage. *Question:* So in context of *Open-iSCSI*, where does the user-land interacts the block layer in the kernel land? I mean, when it comes to kernel land, why we are considering only *scsi_transport_iscsi.c* and *iscsi_tcp.c* codes? Shouldn't the block request go through block layer? As always, thanks in advance :) On Friday, January 10, 2020 at 10:55:34 PM UTC+1, The Lee-Man wrote: > > On Friday, January 10, 2020 at 8:44:05 AM UTC-8, Bobby wrote: >> >> >> Hi, >> >> >> - Question 1: The kernel still contains 2 files? >> - Question 2: Do we still have those diagrams available online? >> >> >> The kernel has many files, but those two files are still present for > open-iscsi.
