6441a57887 staging: rts5139: Use correct USB transfer interval to fix syslog spamming
Using correct transfer interval as specified by the USB endpoint
when doing the interrupt transfer fixes the warning printed by
xhci USB core on every transfer that resulted in spamming
"xhci_queue_intr_tx: 74 callbacks suppressed" to syslog
every 5 seconds.

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.

b3c1afd1fa staging/lustre: fix return value check in libcfs_sock_ioctl()
In case of error, the function sock_alloc_file() returns ERR_PTR()
and never returns NULL. The NULL test in the return value check
should be replaced with IS_ERR().

09b0170e67 staging/lustre/tests: check nr_local in ofd_preprw()
This patch checks the number of bulk I/O RPC pages with
PTLRPC_MAX_BRW_PAGES in ofd_preprw() to avoid
LASSERT(iobuf->dr_npages < iobuf->dr_max_pages) occurring
while larger I/O size is specified.

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.

client.

OST does not support FID yet, then echo client will
still send o_id/o_seq to OST.

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.

50dc198aa8 staging/lustre/debug: quiet noisy console error messages
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.

is applicable, to make the log messages more
informative.

Also, it fixes some small typos and whitespaces
