Pull f2fs updates from Jaegeuk Kim:
"In this round, there are three major updates: (1) folio conversion,
(2) refactoring for mount API conversion, (3) some performance
improvement such as direct IO, checkpoint speed, and IO priority
hints.
For stability, there are patches which add more sanity checks and
fixes some major issues like i_size in atomic write operations and
write pointer recovery in zoned devices.
Enhancements:
- huge folio converion work by Matthew Wilcox
- clean up for mount API conversion by Eric Sandeen
- improve direct IO speed in the overwrite case
- add some sanity check on node consistency
- set highest IO priority for checkpoint thread
- keep POSIX_FADV_NOREUSE ranges and add sysfs entry to reclaim pages
- add ioctl to get IO priority hint
- add carve_out sysfs node for fsstat
Bug fixes:
- disable nat_bits during umount to avoid potential nat entry corruption
- fix missing i_size update on atomic writes
- fix missing discard for active segments
- fix running out of free segments
- fix out-of-bounds access in f2fs_truncate_inode_blocks()
- call f2fs_recover_quota_end() correctly
- fix potential deadloop in prepare_compress_overwrite()
- fix the missing write pointer correction for zoned device
- fix to avoid panic once fallocation fails for pinfile
- don't retry IO for corrupted data scenario
There are many other clean up patches and minor bug fixes as usual"

During a checkpoint, the current active segment X may not be handled
properly. This occurs when segment X has 0 valid blocks and a non-zero
number of discard blocks, for the following reasons:
locate_dirty_segment() does not mark any active segment as a prefree
segment. As a result, segment X is not included in dirty_segmap[PRE], and
f2fs_clear_prefree_segments() skips it when handling prefree segments.
add_discard_addrs() skips any segment with 0 valid blocks, so segment X is
also skipped.
Consequently, no `struct discard_cmd` is actually created for segment X.
However, the ckpt_valid_map and cur_valid_map of segment X are synced by
seg_info_to_raw_sit() during the current checkpoint process. As a result,
it cannot find the missing discard bits even in subsequent checkpoints.
Consequently, the value of sbi->discard_blks remains non-zero. Thus, when
f2fs is umounted, CP_TRIMMED_FLAG will not be set due to the non-zero
sbi->discard_blks.
Relevant code process:
f2fs_write_checkpoint()
f2fs_flush_sit_entries()
list_for_each_entry_safe(ses, tmp, head, set_list) {
for_each_set_bit_from(segno, bitmap, end) {
...
add_discard_addrs(sbi, cpc, false); // skip segment X due to its 0 valid blocks
...
seg_info_to_raw_sit(); // sync ckpt_valid_map with cur_valid_map for segment X
...
}
}
f2fs_clear_prefree_segments(); // segment X is not included in dirty_segmap[PRE] and is skipped
This issue is easy to reproduce with the following operations:
root # mkfs.f2fs -f /dev/f2fs_dev
root # mount -t f2fs /dev/f2fs_dev /mnt_point
root # dd if=/dev/blk_dev of=/mnt_point/1.bin bs=4k count=256
root # sync
root # rm /mnt_point/1.bin
root # umount /mnt_point
root # dump.f2fs /dev/f2fs_dev | grep "checkpoint state"
Info: checkpoint state = 45 : crc compacted_summary unmount ---- 'trimmed' flag is missing
Since add_discard_addrs() can handle active segments with non-zero valid
blocks, it is reasonable to fix this issue by allowing it to also handle
active segments with 0 valid blocks.

In the case of the following call stack for an atomic file,
FI_DIRTY_INODE is set, but FI_ATOMIC_DIRTIED is not subsequently set.
f2fs_file_write_iter
f2fs_map_blocks
f2fs_reserve_new_blocks
inc_valid_block_count
__mark_inode_dirty(dquot)
f2fs_dirty_inode
If FI_ATOMIC_DIRTIED is not set, atomic file can encounter corruption
due to a mismatch between old file size and new data.
To resolve this issue, I changed to set FI_ATOMIC_DIRTIED when
FI_DIRTY_INODE is set. This ensures that FI_DIRTY_INODE, which was
previously cleared by the Writeback thread during the commit atomic, is
set and i_size is updated.

With the new mount API the sb will not be available during initial option
parsing, which will happen before fill_super reads sb from disk.
Now that the sb is no longer directly referenced in parse_options, switch
it to use sbi.
(Note that all calls to f2fs_sb_has_* originating from parse_options will
need to be deferred to later before we can use the new mount API.)

With the new mount api we will not have the superblock available during
option parsing. Prepare for this by passing *sbi rather than *sb.
For now, we are parsing after fill_super has been done, so sbi->sb will
exist. Under the new mount API this will require more care, but do the
simple change for now.

fill_super, so that an sb is not required during option parsing.

The current options parsing function both parses options and validates
them - factor the validation out to reduce the size of the function and
make transition to the new mount API possible, because under the new mount
API, options are parsed one at a time, and cannot all be tested at the end
of the parsing function.

When certain build-time options are disabled, some mount options are not
accepted. For quota and compression, all related options are dismissed
with a single error message. For xattr, acl, and fault injection, each
option is handled individually. In addition, inline_xattr_size was missed
when CONFIG_F2FS_FS_XATTR was disabled.
Collapse xattr, acl, and fault injection errors into a single string, for
simplicity, and handle the missing inline_xattr_size case.

For several zoned storage devices, vendors will provide extra space
which was used for device level GC than specs and F2FS can use this
space for filesystem level GC. To do that, we can reserve the space
using reserved_blocks. However, it is not enough, since this extra
space should not be shown to users. So, with this new sysfs node,
we can hide the space by substracting reserved_blocks from total
bytes.

Commit 8b10d3653735 ("f2fs: introduce FAULT_NO_SEGMENT") allows to trigger
no free segment fault in allocator, then it will update curseg->segno to
NULL_SEGNO, though, CP_ERROR_FLAG has been set, f2fs_write_inode() missed
to check the flag, and access invalid curseg->segno directly in below call
path, then resulting in panic:
- f2fs_write_inode
- f2fs_is_checkpoint_ready
- has_enough_free_secs
- has_not_enough_free_secs
- __get_secs_required
- has_curseg_enough_space
- get_ckpt_valid_blocks
: access invalid curseg->segno
To avoid this issue, let's:
- check CP_ERROR_FLAG flag in prior to f2fs_is_checkpoint_ready() in
f2fs_write_inode().
- in has_curseg_enough_space(), save curseg->segno into a temp variable,
and verify its validation before use.
