e515f17629 scst: Avoid that smatch complains about dead code 
Reported by Bart Van Assche <bvanassche@acm.org>

dd37831c06 qla2x00t: Keep smatch happy 
Smatch reports two warnings on the qla2x00t code:
* sess->local being tested while sess can be NULL.
* The code after the out_unreg_target2x label is only necessary in the procfs build.

d4e66866b1 scst_vdisk: Remove a superfluous test 
If the code after the "out_close:" label is reached it is guaranteed that fd != NULL.
Hence remove the if (fd != NULL) test after that label.

a72b347ccf scst_sysfs: Avoid NULL ptr deref. Fix online documentation 
Avoid that the PRINT_ERROR() statement that complains about too many parameters

0327e15440 Currently there is a possibility that a session name is reused and 
passed to scst_sess_sysfs_create() before scst_sess_sysfs_del() has
finished removing a kobject that is using the same session name. This
patch fixes that. It works by maintaining yet another session list,
namely a list of sessions registered in sysfs, and by using that list to
check for duplicate session names.

fabf9fceda Avoid that removing the scst_local kernel module triggers a deadlock 
when one of its LUNs is a CD-ROM device. sr_block_release() invokes
scst_local_release_adapter() indirectly with sr_mutex held. So if 
scst_local_release_adapter() blocks until the scst_local session has
been freed a deadlock may be triggered if another CD-ROM device has
to be closed in order to free that session. Fix this by changing
scst_local_release_adapter() such that it does not wait until the
session unregistration has finished.
