In case of the COW file, new updates and GC writes are already
separated to page caches of the atomic file and COW file. As some cases
that use the meta inode for GC, there are some race issues between a
foreground thread and GC thread.
To handle them, we need to take care when to invalidate and wait
writeback of GC pages in COW files as the case of using the meta inode.
Also, a pointer from the COW inode to the original inode is required to
check the state of original pages.
For the former, we can solve the problem by using the meta inode for GC
of COW files. Then let's get a page from the original inode in
move_data_block when GCing the COW file to avoid race condition.

The page cache of the atomic file keeps new data pages which will be
stored in the COW file. It can also keep old data pages when GCing the
atomic file. In this case, new data can be overwritten by old data if a
GC thread sets the old data page as dirty after new data page was
evicted.
Also, since all writes to the atomic file are redirected to COW inodes,
GC for the atomic file is not working well as below.
f2fs_gc(gc_type=FG_GC)
- select A as a victim segment
do_garbage_collect
- iget atomic file's inode for block B
move_data_page
f2fs_do_write_data_page
- use dn of cow inode
- set fio->old_blkaddr from cow inode
- seg_freed is 0 since block B is still valid
- goto gc_more and A is selected as victim again
To solve the problem, let's separate GC writes and updates in the atomic
file by using the meta inode for GC writes.

When new_curseg() is allocating a new segment, if mode=fragment:xxx is
switched on in large section scenario, __get_next_segno() will select
the next segno randomly in the range of [0, maxsegno] in order to
fragment segments.
If the candidate segno is free, get_new_segment() will use it directly
as the new segment.
However, if the section of the candidate is not empty, and some other
segments have already been used, and have a different type (e.g NODE)
with the candidate (e.g DATA), GC will complain inconsistent segment
type later.
This could be reproduced by the following steps:
dd if=/dev/zero of=test.img bs=1M count=10240
mkfs.f2fs -s 128 test.img
mount -t f2fs test.img /mnt -o mode=fragment:block
echo 1 > /sys/fs/f2fs/loop0/max_fragment_chunk
echo 512 > /sys/fs/f2fs/loop0/max_fragment_hole
dd if=/dev/zero of=/mnt/testfile bs=4K count=100
umount /mnt
F2FS-fs (loop0): Inconsistent segment (4377) type [0, 1] in SSA and SIT
In order to allow simulating segment fragmentation in large section
scenario, this patch reduces the candidate range:
* if curseg is the last segment in the section, return curseg->segno
to make get_new_segment() itself find the next free segment.
* if curseg is in the middle of the section, select candicate randomly
in the range of [curseg + 1, last_seg_in_the_same_section] to keep
type consistent.

- need_do_checkpoint
- f2fs_space_for_roll_forward
: alloc_valid_block_count was reset to zero,
so, it may missed last data during checkpoint
Let's change to update .total_valid_block_count, .alloc_valid_block_count
and .rf_node_block_count in block_operations(), then their access can be
protected by .node_change and .cp_rwsem lock, so that it can avoid above
race condition.

The lazytime/nolazytime options are now handled in the VFS, and are
never seen in filesystem parsers, so remove handling of these
options from f2fs.
Note: when lazytime support was added in 6d94c74ab8 it made
lazytime the default in default_options() - as a result, lazytime
cannot be disabled (because Opt_nolazytime is never seen in f2fs
parsing).
If lazytime is desired to be configurable, and default off is OK,
default_options() could be updated to stop setting it by default
and allow mount option control.

Let's add sanity check on F2FS_INLINE_DATA flag in inode during GC,

because clks are essential for most drivers. The fix is simple, don't
use clkdev because this is a DT based system where clkdev isn't used.

Highlights:
- Default silead touchscreen driver to 10 fingers and drop 10 finger setting
from all DMI quirks. More of a cleanup then a pure fix, but since the DMI
quirks always get updated through the fixes branch this avoids conflicts.
- Kconfig fix for randconfig builds
- dell-smbios: Fix wrong token data in sysfs
- amd-hsmp: Fix driver poking unsupported hw when loaded manually
The following is an automated git shortlog grouped by driver:
Input:
- silead - Always support 10 fingers
dell-smbios:
- Simplify error handling
- Fix wrong token data in sysfs
platform/x86/amd/hsmp:
- Check HSMP support on AMD family of processors
touchscreen_dmi:
- Use 2-argument strscpy()
- Drop "silead,max-fingers" property
yt2-1380:
- add CONFIG_EXTCON dependency
