Hi, I was looking at the code of linux 2.6 file systems, and cannot find the code that make the current process sleep when it performs a synchronous read. My understanding is, a process will turn to sleep if the content it tries to read is not in the cache. I thought that the process might be put in the request->waiting queue, but after a long time searching, I cannot find such code. So my question is, if a process is going to sleep for reading something from disk, when and where this sleep happens? I am new to this list, and thanks for any help :) -- Kernelnewbies: Help each other learn about the Linux kernel. Archive: http://mail.nl.linux.org/kernelnewbies/ FAQ: http://kernelnewbies.org/faq/
