I am calling during initialization only from detect() entry point.
But I guess, before the detect() is called, scsi layer acquires
the io_request_lock. So, you mean to say that I need to release it
before calling vmalloc() ? I was doing the same thing on 2.2.x
and even on 2.4.0 and it was working fine and now suddenly
it stopped working on 2.4.2. So what are the guidelines for using
vmalloc() if we want to use it in scsi low-level (HBA) driver ?
I am currently using the new error handling code. (use_new_eh_code = TRUE).
