733db573a6 Merge git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending
Pull SCSI target fixes from Nicholas Bellinger:
 "This series is larger than what I'd normally be conformable with
  sending for a -rc5 PULL request..

  However, the bulk of the series is localized to qla2xxx target
  specific fixes that address a number of real-world correctness issues,
  that have been outstanding on the list for ~6 weeks now.  They where
  submitted + verified + acked by the HW LLD vendor, contributed by a
  major production customer of the code, and are marked for v3.18.y
  stable code.

  That said, I don't see a good reason to wait another month to get
  these fixes into mainline.

  Beyond the qla2xx specific fixes, this series also includes:

   - bugfix for a long standing use-after-free in iscsi-target during
     TPG shutdown + demo-mode sessions.

   - bugfix for a >= v4.0 regression OOPs in iscsi-target during a
     iscsi_start_kthreads() failure.

   - bugfix for a >= v4.0 regression hang in iscsi-target for iser
     explicit session/connection logout.

   - bugfix for a iser-target bug where a early CMA REJECTED status
     during login triggers a NULL pointer dereference OOPs.

   - bugfixes for a handful of v4.2-rc1 specific regressions related to
     the larger set of recent backend configfs attribute changes.

  A big thanks to QLogic + Pure Storage for the qla2xxx target bugfixes"

4c7de49a29 perf session env: Rename exit method
The semantic associated in tools/perf/ with foo__delete(instance) is to
release all resources referenced by 'instance' members and then release
the memory for 'instance' itself.

The perf_session_env__delete() function isn't doing this, it just does
the first part, but the space used by 'instance' itself isn't freed, as
it is embedded in a larger structure, that will be freed at other stage.

For these cases we se foo__exit(), i.e. the usage is:

 void foo__delete(foo)
 {
         if (foo) {
                 foo__exit(foo);
                 free(foo);
         }
 }

But when we have something like:

 struct bar {
         struct foo foo;
         . . .
 }

Then we can't really call foo__delete(&bar.foo), we must have this
instead:

 void bar__exit(bar)
 {
         foo__exit(&bar.foo);
         /* free other bar-> resources */
 }

 void bar__delete(bar)
 {
         if (bar) {
		bar__exit(bar);
                free(bar);
         }
 }

So just rename perf_session_env__delete() to perf_session_env__exit().

e33e17ee10 btrfs: add missing discards when unpinning extents with -o discard
When we clear the dirty bits in btrfs_delete_unused_bgs for extents
in the empty block group, it results in btrfs_finish_extent_commit being
unable to discard the freed extents.

The block group removal patch added an alternate path to forget extents
other than btrfs_finish_extent_commit.  As a result, any extents that
would be freed when the block group is removed aren't discarded.  In my
test run, with a large copy of mixed sized files followed by removal, it
left nearly 2/3 of extents undiscarded.

To clean up the block groups, we add the removed block group onto a list
that will be discarded after transaction commit.

e44163e177 btrfs: explictly delete unused block groups in close_ctree and ro-remount
The cleaner thread may already be sleeping by the time we enter
close_ctree.  If that's the case, we'll skip removing any unused
block groups queued for removal, even during a normal umount.
They'll be cleaned up automatically at next mount, but users
expect a umount to be a clean synchronization point, especially
when used on thin-provisioned storage with -odiscard.  We also
explicitly remove unused block groups in the ro-remount path
for the same reason.

499f377f49 btrfs: iterate over unused chunk space in FITRIM
Since we now clean up block groups automatically as they become
empty, iterating over block groups is no longer sufficient to discard
unused space.

This patch iterates over the unused chunk space and discards any regions
that are unallocated, regardless of whether they were ever used.  This is
a change for btrfs but is consistent with other file systems.

We do this in a transactionless manner since the discard process can take
a substantial amount of time and a transaction would need to be started
before the acquisition of the device list lock.  That would mean a
transaction would be held open across /all/ of the discards collectively.
In order to prevent other threads from allocating or freeing chunks, we
hold the chunks lock across the search and discard calls.  We release it
between searches to allow the file system to perform more-or-less
normally.  Since the running transaction can commit and disappear while
we're using the transaction pointer, we take a reference to it and
release it after the search.  This is safe since it would happen normally
at the end of the transaction commit after any locks are released anyway.
We also take the commit_root_sem to protect against a transaction starting
and committing while we're running.

86557861df btrfs: skip superblocks during discard
Btrfs doesn't track superblocks with extent records so there is nothing
persistent on-disk to indicate that those blocks are in use.  We track
the superblocks in memory to ensure they don't get used by removing them
from the free space cache when we load a block group from disk.  Prior
to 47ab2a6c6a (Btrfs: remove empty block groups automatically), that
was fine since the block group would never be reclaimed so the superblock
was always safe.  Once we started removing the empty block groups, we
were protected by the fact that discards weren't being properly issued
for unused space either via FITRIM or -odiscard.  The block groups were
still being released, but the blocks remained on disk.

In order to properly discard unused block groups, we need to filter out
the superblocks from the discard range.  Superblocks are located at fixed
locations on each device, so it makes sense to filter them out in
btrfs_issue_discard, which is used by both -odiscard and FITRIM.

4d89d377bb btrfs: btrfs_issue_discard ensure offset/length are aligned to sector boundaries
It's possible, though unexpected, to pass unaligned offsets and lengths
to btrfs_issue_discard.  We then shift the offset/length values to sector
units.  If an unaligned offset has been passed, it will result in the
entire sector being discarded, possibly losing data.  An unaligned
length is safe but we'll end up returning an inaccurate number of
discarded bytes.

This patch aligns the offset to the 512B boundary, adjusts the length,
and warns, since we shouldn't be discarding on an offset that isn't
aligned with our sector size.

d91de093d9 usb: musb: sunxi: Add support for musb controller in A33 SoC
The A33 SoC uses the same musb controller as found on the A31 and later,
but allwinner has removed the configdata register, this commit adds special
handling for this.

132e237757 usb: musb: sunxi: Add support for musb controller in A31 SoC
The A31 SoC uses the same musb controller as found in earlier SoCs, but it
is hooked up slightly different. Its SRAM is private and no longer controlled
through the SRAM controller, and its reset is controlled via a separate
reset controller. This commit adds support for this setup.

744543c599 usb: musb: sunxi: Add support for the Allwinner sunxi musb controller
This is based on initial code to get the Allwinner sunxi musb controller
supported by Chen-Yu Tsai and Roman Byshko.

This adds support for the Allwinner sunxi musb controller in both host only
and otg mode. Peripheral only mode is not supported, as no boards use that.

This has been tested on a cubietruck (A20 SoC) and an UTOO P66 tablet
(A13 SoC) with a variety of devices in host mode and with the g_serial gadget
driver in peripheral mode, plugging otg / host cables in/out a lot of times
in all possible imaginable plug orders.

4cfbd95232 usb: gadget: f_obex: use bind_deactivated flag
Use bind_deactivated flag instead of calling usb_function_deactivate()
in function bind(). Field 'can_activate' in struct f_obex is no longer
needed as setting 'bind_deactivated' flag makes us sure, that the function
will be binded only if deactivation can be performed successfully.

d5bb9b81db usb: composite: add bind_deactivated flag to usb_function
This patch introduces 'bind_deactivated' flag in struct usb_function.
Functions which don't want to be activated automatically after bind should
set this flag, and when they start to be ready to work they should call
usb_function_activate().

When USB function sets 'bind_deactivated' flag, initial deactivation
counter is incremented automatically, so there is no need to call
usb_function_deactivate() in function bind.

5601250bb1 usb: composite: fix usb_function_activate/deactivate functions
Using usb_gadget_disconnect to make gadget temporarily invisible to host
doesn't provide desired result, because gadget is connected immediately
after binding regardless to previous usb_gadget_disconnect() calls.

For this reason we use usb_gadget_deactivate() instead of
usb_gadget_disconnect() to make it working as expected.
