Because invalidate_mapping_pages() will skip invalidating page which

we need to use truncate_inode_pages_range() instead of

After we inject fault into f2fs_is_valid_blkaddr() during truncation,
a) it missed to increase @nr_free or @valid_blocks
b) it can cause in blkaddr leak in truncated dnode
Which may cause inconsistent status.
This patch separates FAULT_BLKADDR_CONSISTENCE from FAULT_BLKADDR,
and rename FAULT_BLKADDR to FAULT_BLKADDR_VALIDITY
so that we can:
a) use FAULT_BLKADDR_CONSISTENCE in f2fs_truncate_data_blocks_range()
to simulate inconsistent issue independently, then it can verify fsck
repair flow.
b) FAULT_BLKADDR_VALIDITY fault will not cause any inconsistent status,
we can just use it to check error path handling in kernel side.

In this round, we've got a huge number of patches that improve code readability
along with minor bug fixes, while we've mainly fixed some critical issues in
recently-added per-block age-based extent_cache, atomic write support, and some
folio cases.
Enhancement:
- add sysfs nodes to set last_age_weight and manage discard_io_aware_gran
- show ipu policy in debugfs
- reduce stack memory cost by using bitfield in struct f2fs_io_info
- introduce trace_f2fs_replace_atomic_write_block
- enhance iostat support and adds flush commands
Bug fix:
- revert "f2fs: truncate blocks in batch in __complete_revoke_list()"
- fix kernel crash on the atomic write abort flow
- call clear_page_private_reference in .{release,invalid}_folio
- support .migrate_folio for compressed inode
- fix cgroup writeback accounting with fs-layer encryption
- retry to update the inode page given data corruption
- fix kernel crash due to null io->bio
- fix some bugs in per-block age-based extent_cache:
a. wrong calculation of block age
b. update age extent in f2fs_do_zero_range()
c. update age extent correctly during truncation

Merge tag 'f2fs-for-6.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs
Pull f2fs updates from Jaegeuk Kim:
"In this round, we've got a huge number of patches that improve code
readability along with minor bug fixes, while we've mainly fixed some
critical issues in recently-added per-block age-based extent_cache,
atomic write support, and some folio cases.
Enhancements:
- add sysfs nodes to set last_age_weight and manage
discard_io_aware_gran
- show ipu policy in debugfs
- reduce stack memory cost by using bitfield in struct f2fs_io_info
- introduce trace_f2fs_replace_atomic_write_block
- enhance iostat support and adds flush commands
Bug fixes:
- revert "f2fs: truncate blocks in batch in __complete_revoke_list()"
- fix kernel crash on the atomic write abort flow
- call clear_page_private_reference in .{release,invalid}_folio
- support .migrate_folio for compressed inode
- fix cgroup writeback accounting with fs-layer encryption
- retry to update the inode page given data corruption
- fix kernel crash due to NULL io->bio
- fix some bugs in per-block age-based extent_cache:
- wrong calculation of block age
- update age extent in f2fs_do_zero_range()
- update age extent correctly during truncation"
