To close sget() races we'll need to be able to set cifs_sb up before
we get the superblock, so we'll want to be able to do cifs_mount()
earlier.  Fortunately, it's easy to do - setting ->s_maxbytes can
be done in cifs_read_super(), ditto for ->s_time_gran and as for
putting MS_POSIXACL into ->s_flags, we can mirror it in ->mnt_cifs_flags

if we get to out_super with ->s_root already set (e.g. with
cifs_get_root() failure), we'll end up with cifs_put_super()
called and ->mountdata freed twice.  We'll also get cifs_sb
freed twice and cifs_sb->local_nls dropped twice.  The problem
is, we can get to out_super both with and without ->s_root,
which makes ->put_super() a bad place for such work.

Switch to ->kill_sb(), have all that work done there after
kill_anon_super().  Unlike ->put_super(), ->kill_sb() is
called by deactivate_locked_super() whether we have ->s_root
or not.

This patch fixes a bug in ft_send_tm() that was incorrectly calling
ft_get_lun_for_cmd() -> transport_get_lun_for_cmd(), instead of using
transport_get_lun_for_tmr() for the proper struct se_lun lookup
that was triggering an OOPs in the se_cmd->tmr_req failure path.

This patch fixes the issue by re-arranging the codepath where
transport_get_lun_for_tmr() is called after tmr request is allocated and
made it available as part of se_cmd.

It also drops the now unnecessary ft_get_lun_for_cmd() unpacking code, and
uses scsilun_to_int() directly ahead of transport_get_lun_for_cmd() and
transport_get_lun_for_tmr() usage.

This patch fixes a number of cases in target core using an incorrectly

	if (strlen(foo) > SOME_MAX_SIZE)

As strlen() returns the number of characters in the string not counting
the NULL character at the end.  So if you do something like:

        char buf[10];

        if (strlen("0123456789") > 10)
                return -ETOOLONG;
        snprintf(buf, 10, "0123456789");
        printf("%s\n", buf);

then the last "9" gets chopped off and only "012345678" is printed.

Plus I threw in one small related cleanup.

In the original code, there were several places inside the
target_fabric_configfs_init() function that returned NULL on error
and one place the returned an ERR_PTR.  There are two places that
call this function and they only check for NULL returns; they don't
check for ERR_PTRs.  So I've changed the ERR_PTR so now the function
only returns NULL on error.

This patch fixes two possible NULL pointer dereferences in target v4.0
code where se_tmr release path in core_tmr_release_req() can OOPs upon
transport_get_lun_for_tmr() failure by attempting to access se_device or
se_tmr->tmr_list without a valid member of se_device->tmr_list during
transport_free_se_cmd() release.  This patch moves the se_tmr->tmr_dev
pointer assignment in transport_get_lun_for_tmr() until after possible
-ENODEV failures during unpacked_lun lookup.

This addresses an OOPs originally reported with LIO v4.1 upstream on
.39 code here:
