  f2fs: show more discard status by sysfs (2023-12-26 13:07:26 -0800)

----------------------------------------------------------------
f2fs update for 6.8-rc1

In this series, we've some progress to support Zoned block device regarding to
the power-cut recovery flow and enabling checkpoint=disable feature which is
essential for Android OTA. Other than that, some patches touched sysfs entries
and tracepoints which are minor, while several bug fixes on error handlers and
compression flows are good to improve the overall stability.

Enhancement:
 - enable checkpoint=disable for zoned block device
 - sysfs entries such as discard status, discard_io_aware, dir_level
 - tracepoints such as f2fs_vm_page_mkwrite(), f2fs_rename(), f2fs_new_inode()
 - use shared inode lock during f2fs_fiemap() and f2fs_seek_block()

Bug fix:
 - address some power-cut recovery issues on zoned block device
 - handle errors and logics on do_garbage_collect(), f2fs_reserve_new_block(),
   f2fs_move_file_range(), f2fs_recover_xattr_data()
 - don't set FI_PREALLOCATED_ALL for partial write
 - fix to update iostat correctly in f2fs_filemap_fault()
 - fix to wait on block writeback for post_read case
 - fix to tag gcing flag on page during block migration
 - restrict max filesize for 16K f2fs
 - fix to avoid dirent corruption
 - explicitly null-terminate the xattr list

There are also several clean-up patches to remove dead codes and better
readability.
