The cast to u16 in min_t() confuses static analysis because it truncates the int to u16 so I've fixed the declaration to reflect that "sense_len" is just a u16. Also there was a call to cpu_to_be16() which I've changed to be16_to_cpu(). The functions are equivalent, but obviously the hardware is big endian and we're doing the min_t() comparison on CPU endian values. This whole patch is just a cleanup and doesn't affect how the code works.

If the userspace apps do try to manage the kernel ones it can get the driver/fw out of sync and cause the user to loose the root disk, oopses or ping ponging becasue userspace wants to do one thing but the kernel manager thought we are trying to do another. This patch fixes the problem by just exporting the pid of the entity that created the session. Userspace programs like iscsid, iscsiadm, iscsistart, qlogic's tools, etc, can then figure out which sessions they own and only manage them.
