without CIP_DBC_IS_END_EVENT
For IR context, ALSA IEC 61883-1/6 engine uses initial value of data
block counter as UINT_MAX, to detect first isochronous packet in the
middle of packet streaming.
At present, when CIP_DBC_IS_END_EVENT is not used (i.e. for drivers except
for ALSA fireworks driver), the initial value is used as is for
tracepoints event. However, the engine can detect the value of dbc field
in the payload of first isochronous packet and the value should be assigned
to the event.
This commit fixes the bug.

This is a very big update, mainly thanks to Morimoto-san's refactoring
work and some fairly large new drivers.
- Lots more work on moving towards a component based framework from
Morimoto-san.
- Support for force disconnecting muxes from Jerome Brunet.
- New drivers for Cirrus Logic CS47L35, CS47L85 and CS47L90, Conexant

Commit e450f4d1a5d6 ("ceph: pass inclusive lend parameter to
filemap_write_and_wait_range()") fixed the end offset parameter used to
call filemap_write_and_wait_range and invalidate_inode_pages2_range.
Unfortunately it missed truncate_inode_pages_range, introducing a
regression that is easily detected by xfstest generic/130.
The problem is that when doing direct IO it is possible that an extra page
is truncated from the page cache when the end offset is page aligned.
This can cause data loss if that page hasn't been sync'ed to the OSDs.
While there, change code to use PAGE_ALIGN macro instead.

Invalid object maps are not trusted, but still updated. Note that we

rbd_wait_state_locked() is built around rbd_dev->lock_waitq and blocks
rbd worker threads while waiting for the lock, potentially impacting
other rbd devices. There is no good way to pass an error code into
image request state machines when acquisition fails, hence the use of
RBD_DEV_FLAG_BLACKLISTED for everything and various other issues.
Introduce rbd_dev->acquiring_list and move acquisition into image
request state machine. Use rbd_img_schedule() for kicking and passing
error codes. No blocking occurs while waiting for the lock, but
rbd_dev->lock_rwsem is still held across lock, unlock and set_cookie
calls.
Always acquire the lock on "rbd map" to avoid associating the latency
of acquiring the lock with the first I/O request.
A slight regression is that lock_timeout is now respected only if lock
acquisition is triggered by "rbd map" and not by I/O. This is somewhat
compensated by the fact that we no longer block if the peer refuses to
release lock -- I/O is failed with EROFS right away.

Syncing OSD requests doesn't really work. A single image request may
be comprised of multiple object requests, each of which can go through
a series of OSD requests (original, copyups, etc). On top of that, the
OSD cliest may be shared with other rbd devices.
What we want is to ensure that all in-flight image requests complete.
Introduce rbd_dev->running_list and block in RBD_LOCK_STATE_RELEASING
until that happens. New OSD requests may be started during this time.
Note that __rbd_img_handle_request() acquires rbd_dev->lock_rwsem only
if need_exclusive_lock() returns true. This avoids a deadlock similar
to the one outlined in the previous commit between unlock and I/O that
doesn't require lock, such as a read with object-map feature disabled.

Quiesce exclusive lock at the top of rbd_reacquire_lock() instead
of only when ceph_cls_set_cookie() fails. This avoids a deadlock on
rbd_dev->lock_rwsem.
If rbd_dev->lock_rwsem is needed for I/O completion, set_cookie can
hang ceph-msgr worker thread if set_cookie reply ends up behind an I/O
reply, because, like lock and unlock requests, set_cookie is sent and
waited upon with rbd_dev->lock_rwsem held for write.

Since the dawn of time it had been assumed that a single object request
spawns a single OSD request. This is already impacting copyup: instead
of sending empty and current snapc copyups together, we wait for empty
snapc OSD request to complete in order to reassign obj_req->osd_req
with current snapc OSD request. Looking further, updating potentially
hundreds of snapshot object maps serially is a non-starter.
Replace obj_req->osd_req pointer with obj_req->osd_reqs list. Use
osd_req->r_private_item for linkage.

The convention with xattrs is to not store the termination with string
data, given that it returns the length. This is how setfattr/getfattr
operate.
Most of ceph's virtual xattr routines use snprintf to plop the string
directly into the destination buffer, but snprintf always NULL
terminates the string. This means that if we send the kernel a buffer
that is the exact length needed to hold the string, it'll end up
truncated.
Add a ceph_fmt_xattr helper function to format the string into an
on-stack buffer that should always be large enough to hold the whole
thing and then memcpy the result into the destination buffer. If it does
turn out that the formatted string won't fit in the on-stack buffer,
then return -E2BIG and do a WARN_ONCE().
Change over most of the virtual xattr routines to use the new helper. A
couple of the xattrs are sourced from strings however, and it's
difficult to know how long they'll be. Just have those memcpy the result
in place after verifying the length.
