Because they may be allocated by vmalloc.

Servers can defer destaging any data and updating the mtime until close().
This means that if we do a setinfo to modify the mtime while other handles
are open for write the server may overwrite our setinfo timestamps when
if flushes the file on close() of the writeable handle.
To solve this we add an explicit flush when the mtime is about to
be updated.
This fixes "cp -p" to preserve mtime when copying a file onto an SMB2 share.

We can cut one third of the traffic on open by not querying the
inode number explicitly via SMB3 query_info since it is now
returned on open in the qfid context.
This is better in multiple ways, and
speeds up file open about 10% (more if network is slow).

after the eDP got blanked. Since smooth brightness is enabled,
the driver will make a call into the DMCU to ramp the brightness.
The DMCU would try to enable ABM to do so. But since the display is

[WHY]
Currently we don't wait for blacklight programming completion in DMCU
when setting backlight level. Some sequences such as PSR static screen
event trigger reprogramming requires it to be complete.
[How]
Add generic wait for dmcu command completion in set backlight level.

[why]
The current code will not wait for the entire frame
after global unlock.
This causes dsc dynamic target bpp update corruption when
there is a surface update immediately happens after this.
[how]
Wait for the entire whole frame after unlock before continuing
the rest of stream and surface update.

[Why]
For DCE110, DCE112 and DCE120 the max_clks_by_state for the clk_mgr are
copied from their respective table before the call to
dce_clk_mgr_construct, but then dce_clk_mgr_construct overwrites
these with the dce80_max_clks_by_state.
[How]
Copy these after we call dce_clk_mgr_construct so we're using the
right tables.

We reset the optimized_required in atomic_plane_disable

Optimize directly after each time plane is removed.

[Why]
Fixes issue when we have a display connected using a passive
dongle and then emulate over it using a DP connection at 1 x 1.62 Ghz.
System hangs because register bus returns back 0xFFFFFFFF for all
register reads after setting register DIG_BE_CNTL in
dcn10_link_encoder_connect_dig_be_to_fe(). Hang occurs later
when trying to do a register read.
[How]
At the start of the emulation, dc_link_set_preferred_link_settings()
and dp_retrain_link_dp_test() is called, even though it is connected
using a passive dongle.
Add an extra condition in dp_retrain_link_dp_test() to check for
link->dongle_max_pix_clk > 0. This is the only way we know if the
connection is using passive dongle so we don't retrain DP.

[Why]
There are certain MST displays (i.e. Dell P2715Q)
that although have the MST feature set to off may still
report it is a branch device and a non-zero
value for downstream port present.
This can lead to us incorrectly classifying a
dp dongle connection as being active and
disabling the audio endpoint for the display.
[How]
Modified the placement and
condition used to assign
the is_branch_dev bit.

On some modes SMU will be in infinite loop state at boot, this is
because driver assumes p_state_support is false, but this is the
opposite of the assumed boot state by SMU. we optimize away

when we init clk manager, init pstate to true, so it matches driver load
