Hi Dongsheng,
I'm working on it, next step I'm gathering some testing data and
upload (very sorry for the delay...)
Thanks for the comment.
One of the main concerns to alleviate this issue with the writeback
process is that we need to minimize the impact on the client IO
performance.
The ECS EF20EA laptop ships an AXP288 but it is actually using a
different, separate FG chip for AC and battery monitoring. On this
laptop we need to keep using the regular ACPI driver and disable the
AXP288 FG to avoid reporting two batteries to userspace.

Returning 0 is no more an error case with MV88E6393 family
which has serdes lane numbers 0, 9 or 10.
So with this change .serdes_get_lane will return lane number

Yeah, fair enough.

Trivial cleanup:
f2fs_balance_fs(sbi, true);
+ f2fs_balance_fs(F2FS_I_SB(inode), true);
Ditto,
Jaegeuk could fix this directly?
Thanks,

To me it looks like protkey.len is generated programmatically in
pkey_genprotkey/pkey_clr2protkey
and this
In contexts like suspend, shutdown and error handling, we need to suspend
devfreq to make sure these contexts won't be disturbed by clock scaling.
However, suspending devfreq is not enough since users can still trigger a
clock scaling by manipulating the sysfs node clkscale_enable and devfreq
ufshcd_hba_exit() is always called after ufshcd_exit_clk_scaling() and
ufshcd_exit_clk_gating(), so no need to suspend clock scaling again in
ufshcd_hba_exit().
