Changed usbip_network, usbip_attach, usbip_list, and usbipd to use
and propagate the new error codes in server reply messages.
usbip_net_recv_op_common() is changed to take a pointer to status
return the status returned in the op_common.status to callers.
usbip_attach and usbip_list use the common interface to print error
messages to indicate why the request failed.
With this change the messages say why a request failed:
- when a client requests a device that is already exported:
usbip attach -r server_name -b 3-10.2
usbip: error: Attach Request for 3-10.2 failed - Device busy (exported)
- when a client requests a device that isn't exportable,
usbip attach -r server_name -b 3-10.4
usbip: error: Attach Request for 3-10.4 failed - Device not found

This patch reverts the commit 835e4241e7 ("usb: host: xhci-plat:
enable clk in resume timing") because this driver also has runtime PM
and the commit 560869100b ("clk: renesas: cpg-mssr: Restore module
clocks during resume") will restore the clock on R-Car H3 environment.
If the xhci_plat_suspend() disables the clk, the system cannot enable
the clk in resume like the following behavior:
< In resume >
- genpd_resume_noirq() runs and enable the clk (enable_count = 1)
- cpg_mssr_resume_noirq() restores the clk register.
-- Since the clk was disabled in suspend, cpg_mssr_resume_noirq()
will disable the clk and keep the enable_count.
- Even if xhci_plat_resume() calls clk_prepare_enable(), since
the enable_count is 1, the clk will be not enabled.
After this patch is applied, the cpg-mssr driver will save the clk
as enable, so the clk will be enabled in resume.

The following commit:
commit aa4d86163e ("block: loop: switch to VFS ITER_BVEC")
replaced __do_lo_send_write(), which used ITER_KVEC iterators, with
lo_write_bvec() which uses ITER_BVEC iterators. In this change, though,
the WRITE flag was lost:
- iov_iter_kvec(&from, ITER_KVEC | WRITE, &kvec, 1, len);
+ iov_iter_bvec(&i, ITER_BVEC, bvec, 1, bvec->bv_len);
This flag is necessary for the DAX case because we make decisions based on
whether or not the iterator is a READ or a WRITE in dax_iomap_actor() and
in dax_iomap_rw().
We end up going through this path in configurations where we combine a PMEM
device with 4k sectors, a loopback device and DAX. The consequence of this
missed flag is that what we intend as a write actually turns into a read in
the DAX code, so no data is ever written.
The very simplest test case is to create a loopback device and try and
write a small string to it, then hexdump a few bytes of the device to see
if the write took. Without this patch you read back all zeros, with this
you read back the string you wrote.
For XFS this causes us to fail or panic during the following xfstests:
xfs/074 xfs/078 xfs/216 xfs/217 xfs/250
For ext4 we have a similar issue where writes never happen, but we don't
currently have any xfstests that use loopback and show this issue.
Fix this by restoring the WRITE flag argument to iov_iter_bvec(). This
causes the xfstests to all pass.

This problem was introduced by commit 02a7c234e5 ("rcu: Suppress

of rt_mutex_futex_unlock() with irq off.
To fix this, replace the *lock_irq() in rt_mutex_futex_unlock() with
*lock_irq{save,restore}() to make it safe to call rt_mutex_futex_unlock()
with irq off.

Disable the kprobe probing of the entry trampoline:
.entry_trampoline is a code area that is used to ensure page table
isolation between userspace and kernelspace.
At the beginning of the execution of the trampoline, we load the
kernel's CR3 register. This has the effect of enabling the translation
of the kernel virtual addresses to physical addresses. Before this
happens most kernel addresses can not be translated because the running
process' CR3 is still used.
If a kprobe is placed on the trampoline code before that change of the
CR3 register happens the kernel crashes because int3 handling pages are
not accessible.
To fix this, add the .entry_trampoline section to the kprobe blacklist
to prohibit the probing of code before all the kernel pages are
accessible.

In ctx_resched(), EVENT_FLEXIBLE should be sched_out when EVENT_PINNED is
added. However, ctx_resched() calculates ctx_event_type before checking
this condition. As a result, pinned events will NOT get higher priority
than flexible events.
The following shows this issue on an Intel CPU (where ref-cycles can
only use one hardware counter).
1. First start:
perf stat -C 0 -e ref-cycles -I 1000
2. Then, in the second console, run:
perf stat -C 0 -e ref-cycles:D -I 1000
The second perf uses pinned events, which is expected to have higher
priority. However, because it failed in ctx_resched(). It is never
run.
This patch fixes this by calculating ctx_event_type after re-evaluating
event_type.

Merge tag 'drm-misc-fixes-2018-03-07' of git://anongit.freedesktop.org/drm/drm-misc into drm-fixes
sun4i fixes on clk, division by zero and LVDS.
* tag 'drm-misc-fixes-2018-03-07' of git://anongit.freedesktop.org/drm/drm-misc:
drm/sun4i: crtc: Call drm_crtc_vblank_on / drm_crtc_vblank_off
drm/sun4i: rgb: Fix potential division by zero
drm/sun4i: tcon: Reduce the scope of the LVDS error a bit
drm/sun4i: Release exclusive clock lock when disabling TCON
drm/sun4i: Fix dclk_set_phase
This USB-SATA controller seems to be similar with JMicron bridge
152d:2566 already on the list. Adding it here fixes "Invalid
field in cdb" errors.

We do want to respect the FLUSH_SYNC argument to nfs_commit_inode() to
ensure that all outstanding COMMIT requests to the inode in question are
complete. Currently we may exit early from both nfs_commit_inode() and
nfs_write_inode() even if there are COMMIT requests in flight, or unstable
writes on the commit list.
In order to get the right semantics w.r.t. sync_inode(), we don't need
to have nfs_commit_inode() reset the inode dirty flags when called from
nfs_wb_page() and/or nfs_wb_all(). We just need to ensure that
nfs_write_inode() leaves them in the right state if there are outstanding
commits, or stable pages.

Ensure that we hold a reference to the layout header when processing
the pNFS return-on-close so that the refcount value does not inadvertently
go to zero.

Corrected four outstanding issues in the transport around sqsize.
1: Create Connection LS is sending the 1's-based sqsize, should be
sending the 0's-based value.
2: allocation of hw queue is using the 0's-base size. It should be
using the 1's-based value.
3: normalization of ctrl.sqsize by MQES is using MQES+1 (1's-based
value). It should be MQES (0's-based value).
4: Missing clause to ensure queue_count not larger than ctrl->sqsize.
Corrected by:
Clean up routines that pass queue size around. The queue size value is
the actual count (1's-based) value and determined from ctrl->sqsize + 1.
Routines that send 0's-based value adapt from queue size.
Sset ctrl->sqsize properly for MQES.
Added clause to nsure queue_count not larger than ctrl->sqsize + 1.

a block device was detached/re-attached."
