78f304d06c iio:trigger:interrupt fix formatting of rsize variable in name
The name includes irq_res->start which of type resource_size_t not integer.
We could in theory use %pa for this but then it would be in hex and also
that causes a warning about incorrect types anyway.  Hence just
use the irq local variable we assigned the line above.

3c1e02dbb3 staging:iio:triggers:interrupt trigger - one per platform device.
Switching from one platform device registering a lot of triggers
to one for each trigger simplifies the code somewhat. It would be
relatively unusual to have more than a couple of such devices
registered so this change will not result in much additional overhead.

b164935b38 staging: MIPS: add Octeon USB HCD support
Add support for Octeon USB HCD. Tested on EdgeRouter Lite with USB

to make it work with 3.10-rc3.

Check to see if allocation by kzalloc() or usb_alloc_urb() was unsuccessful
immediately after the allocation. Exit from the function can be right at that
point in case of allocation failure.
This avoids unnecessary use of usb_alloc_urb() & usb_free_urb() if kzalloc()
returns NULL.
Also, makes the code better structured & easier to understand.

c5c141dfe7 staging: rts5139: Fix SD card detection on Samsung NP730U3E Ultrabook
The timeout detection implemented in this driver isn't very
robust. Although the USB interrupt transfer was successful,
the polling thread often reported timeouts because the 50ms
had expired before it got scheduled, and the SD card wasn't
detected. Increasing it to 100ms, as used in other places of
this driver, makes it work.

PTLRPC_MAX_BRW_PAGES in ofd_preprw() to avoid

The patch also fixes echo_client_prep_commit() to reuse
the env context so as to avoid LASSERT(info->fti_exp == NULL)
occurring while the bulk I/O size is larger than
PTLRPC_MAX_BRW_SIZE.

The patch also improves obdfilter-survey to handle the
case while interoprating with old server.

f57d9a72d4 staging/lustre/mdt: set ATTR_xTIME_SET to make atime update properly
To make atime update properly between 1.8 client and 2.x server,
this patch includes the following fixes:
- if MDS_ATTR_xTIME is set without MDS_ATTR_xTIME_SET and the client
  does not have OBD_CONNECT_FULL20, convert it to LA_xTIME in
  mdt_setattr_unpack().
- set both MDS_ATTR_xTIME | MDS_ATTR_xTIME_SET for timestamps in
  ll_prepare_close(). This allows us to fix the server-side timestamp
  setting in the future.
- remove attr_unpack() and convert the flags from MDS_ATTR_ to LA_*
  directly in mdt_attr_valid_xlate() instead.
- improve sanityn.sh test_23().

e11b0b167d staging/lustre/changelog: fix CL_LAYOUT comment, string
Fix the CL_LAYOUT comment, since it is possible that layout swap
could be used in cases where the file content is changed.  I don't
think there are any real world use cases for this, but that depends
on what tools are being used on the filesystem.

Also change the "LAYOUT" string for this ChangeLog record type to
be "LYOUT" to match the convention of other strings to only be
5 characters long.

9d8654397d staging/lustre/ost: Ensure dirty flushed on fiemap ioctl
Data corruption is possible if cp(coreutils) uses FIEMAP to obtain
data holes in shared file, since there could be dirty cache on
other clients which hasn't been flushed back.

To ensure all the dirty on remote clients being flushed back on
fiemap ioctl, we'd acquire ldlm lock on server side for fiemap,
unless the local client (which invoke fiemap) has cached lock.

e377988ed8 staging/lustre/changelog: fix CL_LAYOUT, accept all types
In order to avoid compatibility issues with older ChangeLog consumers,
change the new CL_LAYOUT record to use the value previously assigned
to CL_IOCTL.  The CL_IOCTL type was never used anywhere, and it didn't
really make any sense as a ChangeLog record, since it could really
mean anything at all.

The changelog_show_cb() function is renamed to changelog_kkuc_cb(),
since it is really about consuming the ChangeLog and passing it up to
the kernel-user-coms interface.  At some point we should consider to
implement a DBUS-based ChangeLog interface as well.

The changelog_kkuc_cb() "sanity check" on cr_type was removed, since
there is no reason the client kernel needs to know every record type
that is being passed to userspace.  It is up to the client tool to
determine what records that it can process.

edb4973dbc staging/lustre/lprocfs: use stats counter index for *pos
In lprocfs_stats_seq_{start,next,show,stop}() encode the counter index
(rather than the counter address) into *pos. Doing so simplifies these
functions and fixes a bug in the case of per-CPU stats where no stats
would be displayed at all if no events had yet occurred on CPU 0.

3b2f75fd59 staging/lustre/ost: check pre 2.4 echo client in obdo validation
Because old echo client still uses o_id/o_seq for objid,
but new echo client will uses FID for the objid. Add
OBD_CONNECT_FID for 2.4 echo client, so 2.4 OST will
convert o_id/o_seq to FID if the request from old echo
client.

Add local flag OBD_FL_OSTID for o_flags to indicate
OST does not support FID yet, then echo client will
still send o_id/o_seq to OST.

ptlrpcd_add_req() will wake_up other process, do not hold a spinlock
before calling ptlrpcd_queue_work()->ptlrpcd_add_req().

If current process is allocating memory, memory shrinker could get to
osc_lru_del(), don't call osc_lru_shrink() further since it could
lead a long calling chain.

Use static string OES_STRINGS in OSC_EXTENT_DUMP() to reduce stack
footprint.

Alloc crattr on heap for osc_build_rpc() to reduce stack footprint.

bc96917618 staging/lustre/ldlm: suppress useless lock RPC for layout
In ldlm_lock_decref_internal() when l_lvb_data is freed to
reduce memory consumption, LDLM_FL_LVB_READY is not
cleared, so later when the lock is reused lvb is not
updated. But clearing LDLM_FL_LVB_READY forces layout refetch
at each file access, so the better is to remove the optimization.
The use case is after a restore in HSM.

Quiet a number of overly noisy and unhelpful console error
messages.  Improve the format of other nearby errors.

In the case of {lod,lov}_fix_desc_stripe_size(), this doesn't
even need a console message unless it is actually changing
some stripe size that is below the minimum.  Typically it is
only zero and is being bumped up to the default value.
