[SCSI] mpt fusion: fix two potential mem leaks

The Coverity checker spotted two potential memory leaks in
drivers/message/fusion/mptbase.c::mpt_attach().

There are two returns that may leak the storage allocated for 'ioc'

A simple fix would be to simply add two kfree() calls before the return

code so that if we hit the first return condition we don't have to do the

[SCSI] add supported_mode and active_mode attributes to the host

This adds supported_mode and active_mode attributes to
/sys/class/sys_host/hostX/ for specifying the mode that a lld supports
and the currently activated mode. The output format is similar to fc
rport roles:

luce:/sys/class/scsi_host/host0$ cat supported_mode
Initiator
luce:/sys/class/scsi_host/host0$ cat active_mode

the future like this:

luce:/sys/class/scsi_host/host0$ cat supported_mode
Initiator, Target

The supported_mode attribute looks at a scsi_host_template and the
active_mode attribute looks at a scsi_host. We would add a hook to a
scsi_host_template to change the active_mode attribute
dynamically. But now there is no hook since no lld supports that

The Coverity checker noticed that we may overrun a statically allocated

The case is this; In 'struct lpfc_hba' we have

#define LPFC_MAX_HBQS  4
...
struct lpfc_hba {
...
struct hbq_s hbqs[LPFC_MAX_HBQS];
...
};

But then in lpfc_sli_hbqbuf_find() we have this code

hbqno = tag >> 16;
if (hbqno > LPFC_MAX_HBQS)
return NULL;

if 'hbqno' ends up as exactely 4, then we won't return, and then this

list_for_each_entry(d_buf, &phba->hbqs[hbqno].hbq_buffer_list, list) {

will cause an overflow of the statically allocated array at index 4,
since the valid indices are only 0-3.

I propose this patch, that simply changes the 'hbqno > LPFC_MAX_HBQS'

[SCSI] Fix async scanning double-add problems

Stress-testing and some thought has revealed some places where
asynchronous scanning needs some more attention to locking.

 - Since async_scan is a bit, we need to hold the host_lock while
   modifying it to prevent races against other CPUs modifying the word
   that bit is in.  This is probably a theoretical race for the moment,
   but other patches may change that.
 - The async_scan bit means not only that this host is being scanned
   asynchronously, but that all the devices attached to this host are not
   yet added to sysfs.  So we must ensure that this bit is always in sync.
   I've chosen to do this with the scan_mutex since it's already acquired
   in most of the right places.
 - If the host changes state to deleted while we're in the middle of
   a scan, we'll end up with some devices on the host's list which must
   be deleted.  Add a check to scsi_sysfs_add_devices() to ensure the
   host is still running.
 - To avoid the async_scan bit being protected by three locks, the
   async_scan_lock now only protects the scanning_list.

[SCSI] tgt: add I_T nexus support

tgt uses scsi_host as I_T nexus. This works for ibmvstgt because it
creates one scsi_host for one initiator. However, other target drivers
don't work like that.

This adds I_T nexus support, which enable one scsi_host to handle
multiple initiators. New scsi_tgt_it_nexus_create/destroy functions
are expected be called transport classes. For example, ibmvstgt
creates an initiator remote port, then the srp transport calls
tgt_it_nexus_create. tgt doesn't manages I_T nexus, instead it tells
tgtd, user-space daemon, to create a new I_T nexus.

On the receiving the response from tgtd, tgt calls
shost->transportt->it_nexus_response. transports should notify a
lld. The srp transport uses it_nexus_response callback in
srp_function_template to do that.

[GFS2] Revert remounting w/o acl option leaves acls enabled

This reverts commit 569a7b6c2e8965ff4908003b925757703a3d649c. The
code was correct originally. The default setting for ACLs after a
remount should be to be the same as before the remount.

[GFS2] Fix setting of inherit jdata attr

Due to a mix up between the jdata attribute and inherit jdata attribute
it has not been possible to set the inherit jdata attribute on

jdata attribute for directories rather than the jdata attribute as it
did previously. This stems from our need to have the one bit in the
ioctl attr flags mean two different things according to whether the
underlying inode is a directory or not.
