scst: avoid false lockdep complaints about recursive locking
In some cases SCST needs to take multiple locks recursivly, e.g. to lock
all tgt_devs in a session. For this case SCST takes those locks in their
current sort order, e.g. by LUN for tgt_devs, then releases in the
opposite order. Unfortunately, lockdep complains on such actions as
recursive locking, then disables itself. The disabling itself action is
the most unpleasant one leading to lockdep being useless after this point.
Unfortunately, nested locking annotations can't help, because after
free, then alloc again, or after LUN change (in case of tgt_devs) order
of locks can change.
So, this patch implements a way to annotate some lock and unlock actions
as "no lockdep", so lockdep will not track them. It contains related
kernel patches for some kernels.
This is a debug aid only useful only with lockdep enabled kernels.

ib_srpt: Fix a race condition in the initialization code
Initialize port information before registering the CM ID. One of
the functions called by the CM handler (srpt_cm_req_recv())
namely uses the SCST target pointer so that pointer must be
initialized before the CM ID is registered. This patch avoids that
SRP login during ib_srpt initialization sporadically triggers the
following bug:
ib_srpt: Rejecting login with reason 0x10001
BUG: unable to handle kernel NULL pointer dereference at 0000000000000100

ib_srpt: Reduce default value of srpt_sq_size
Reduce the default value of the srpt_sq_size kernel module
parameter from 4096 to 256. This avoids on recent kernels
(e.g. 4.1.0) QP creation causes swiotlb to complain about a
failed allocation.

This patch avoids that the following kernel warning appears while
starting SCST after having loaded APTPL PR information:

2. Make /sys/kernel/scst_tgt/trace_level reflect currently available logging
3. Cleanup unused log levels from /sys/kernel/scst_tgt/trace_level

It could happen, if a non-pass-through dev handler erroneously returned
SCST_EXEC_NOT_COMPLETED and TRAGE_DBG() statements enabled in debug mode.

manager, and change ALUA state. After that the zvol would be in constant busy
state, even if we remove all scst modules.
The problem is that blockio_on_alua_state_change_finish will unconditionally
vdisk_open_fd. But for the above mentioned case, tgt_dev_cnt will be zero, so
the fd is permanently leaked. We fix this by only do vdisk_open_fd when
tgt_dev_cnt is not zero.
